## Summary

This PR fixes `kDO_LAMBDA` token incompatibility between Parser gem and `Prism::Translation::Parser` for lambda `do` block.

### Parser gem (Expected)

Returns `kDO_LAMBDA` token:

```console
$ bundle exec ruby -Ilib -rparser/ruby33 -ve \
'buf = Parser::Source::Buffer.new("example.rb"); buf.source = "-> do end"; p Parser::Ruby33.new.tokenize(buf)[2]'
ruby 3.4.0dev (2024-09-01T11:00:13Z master https://github.com/ruby/prism/commit/eb144ef91e) [x86_64-darwin23]
[[:tLAMBDA, ["->", #<Parser::Source::Range example.rb 0...2>]], [:kDO_LAMBDA, ["do", #<Parser::Source::Range example.rb 3...5>]],
[:kEND, ["end", #<Parser::Source::Range example.rb 6...9>]]]
```

### `Prism::Translation::Parser` (Actual)

Previously, the parser returned `kDO` token when parsing the following:

```console
$ bundle exec ruby -Ilib -rprism -rprism/translation/parser33 -ve \
'buf = Parser::Source::Buffer.new("example.rb"); buf.source = "-> do end"; p Prism::Translation::Parser33.new.tokenize(buf)[2]'
ruby 3.4.0dev (2024-09-01T11:00:13Z master https://github.com/ruby/prism/commit/eb144ef91e) [x86_64-darwin23]
[[:tLAMBDA, ["->", #<Parser::Source::Range example.rb 0...2>]], [:kDO, ["do", #<Parser::Source::Range example.rb 3...5>]],
[:kEND, ["end", #<Parser::Source::Range example.rb 6...9>]]]
```

After the update, the parser now returns `kDO_LAMBDA` token for the same input:

```console
$ bundle exec ruby -Ilib -rprism -rprism/translation/parser33 -ve \
'buf = Parser::Source::Buffer.new("example.rb"); buf.source = "-> do end"; p Prism::Translation::Parser33.new.tokenize(buf)[2]'
ruby 3.4.0dev (2024-09-01T11:00:13Z master https://github.com/ruby/prism/commit/eb144ef91e) [x86_64-darwin23]
[[:tLAMBDA, ["->", #<Parser::Source::Range example.rb 0...2>]], [:kDO_LAMBDA, ["do", #<Parser::Source::Range example.rb 3...5>]],
[:kEND, ["end", #<Parser::Source::Range example.rb 6...9>]]]
```

## Additional Information

Unfortunately, this kind of edge case doesn't work as expected; `kDO` is returned instead of `kDO_LAMBDA`.
However, since `kDO` is already being returned in this case, there is no change in behavior.

### Parser gem

Returns `tLAMBDA` token:

```console
$ bundle exec ruby -Ilib -rparser/ruby33 -ve \
'buf = Parser::Source::Buffer.new("example.rb"); buf.source = "-> (foo = -> (bar) {}) do end"; p Parser::Ruby33.new.tokenize(buf)[2]'

[:kEND, ["end", #<Parser::Source::Range example.rb 26...29>]]]
```

### `Prism::Translation::Parser`

Returns `kDO` token:

```console
$ bundle exec ruby -Ilib -rprism -rprism/translation/parser33 -ve \
'buf = Parser::Source::Buffer.new("example.rb"); buf.source = "-> (foo = -> (bar) {}) do end"; p Prism::Translation::Parser33.new.tokenize(buf)[2]'

[:tRPAREN, [")", #<Parser::Source::Range example.rb 21...22>]], [:kDO, ["do", #<Parser::Source::Range example.rb 23...25>]],
[:kEND, ["end", #<Parser::Source::Range example.rb 26...29>]]]
```

As the intention is not to address such special cases at this point, a comment has been left indicating that this case still returns `kDO`.
In other words, `kDO_LAMBDA` will now be returned except for edge cases after this PR.

This PR fixes a token incompatibility between Parser gem and `Prism::Translation::Parser` for double splat argument.

## Parser gem (Expected)

Returns `tDSTAR` token:

```console
$ bundle exec ruby -Ilib -rparser/ruby33 -ve \
'buf = Parser::Source::Buffer.new("example.rb"); buf.source = "def f(**foo) end"; p Parser::Ruby33.new.tokenize(buf)[2]'

[:kEND, ["end", #<Parser::Source::Range example.rb 13...16>]]]
```

## `Prism::Translation::Parser` (Actual)

Previously, the parser returned `tPOW` token when parsing the following:

```console
$ bundle exec ruby -Ilib -rprism -rprism/translation/parser33 -ve \
'buf = Parser::Source::Buffer.new("example.rb"); buf.source = "def f(**foo) end"; p Prism::Translation::Parser33.new.tokenize(buf)[2]'

```

[:kEND, ["end", #<Parser::Source::Range example.rb 13...16>]]]
```

With this change, the following code could be removed from test/prism/ruby/parser_test.rb:

```diff
-          when :tPOW
-            actual_token[0] = expected_token[0] if expected_token[0] == :tDSTAR
```

`tPOW` is the token type for the behavior of `a ** b`, and its behavior remains unchanged:

```console
$ bundle exec ruby -Ilib -rprism -rprism/translation/parser33 -ve \
'buf = Parser::Source::Buffer.new("example.rb"); buf.source = "a ** b"; p Prism::Translation::Parser33.new.tokenize(buf)[2]'

47742841246c637053dc8dad447c7e5e28182676

This PR fixes a token incompatibility between Parser gem and `Prism::Translation::Parser` for left parenthesis.

## Parser gem (Expected)

Returns `tLPAREN2` token:

```console
$ bundle exec ruby -Ilib -rparser/ruby33 \
-ve 'buf = Parser::Source::Buffer.new("example.rb"); buf.source = "foo(:bar)"; p Parser::Ruby33.new.tokenize(buf)[2]'
ruby 3.4.0dev (2024-09-01T11:00:13Z master https://github.com/ruby/prism/commit/eb144ef91e) [x86_64-darwin23]
[[:tIDENTIFIER, ["foo", #<Parser::Source::Range example.rb 0...3>]], [:tLPAREN2, ["(", #<Parser::Source::Range example.rb 3...4>]],
[:tSYMBOL, ["bar", #<Parser::Source::Range example.rb 4...8>]], [:tRPAREN, [")", #<Parser::Source::Range example.rb 8...9>]]]
```

## `Prism::Translation::Parser` (Actual)

Previously, the parser returned `tLPAREN` token when parsing the following:

```console
$ bundle exec ruby -Ilib -rprism -rprism/translation/parser33 -ve \
'buf = Parser::Source::Buffer.new("example.rb"); buf.source = "foo(:bar)"; p Prism::Translation::Parser33.new.tokenize(buf)[2]'
ruby 3.4.0dev (2024-09-01T11:00:13Z master https://github.com/ruby/prism/commit/eb144ef91e) [x86_64-darwin23]
[[:tIDENTIFIER, ["foo", #<Parser::Source::Range example.rb 0...3>]], [:tLPAREN, ["(", #<Parser::Source::Range example.rb 3...4>]],
[:tSYMBOL, ["bar", #<Parser::Source::Range example.rb 4...8>]], [:tRPAREN, [")", #<Parser::Source::Range example.rb 8...9>]]]
```

After the update, the parser now returns `tLPAREN2` token for the same input:

```console
$ bundle exec ruby -Ilib -rprism -rprism/translation/parser33 -ve \
'buf = Parser::Source::Buffer.new("example.rb"); buf.source = "foo(:bar)"; p Prism::Translation::Parser33.new.tokenize(buf)[2]'
ruby 3.4.0dev (2024-09-01T11:00:13Z master https://github.com/ruby/prism/commit/eb144ef91e) [x86_64-darwin23]
[[:tIDENTIFIER, ["foo", #<Parser::Source::Range example.rb 0...3>]], [:tLPAREN2, ["(", #<Parser::Source::Range example.rb 3...4>]],
[:tSYMBOL, ["bar", #<Parser::Source::Range example.rb 4...8>]], [:tRPAREN, [")", #<Parser::Source::Range example.rb 8...9>]]]
```

The `PARENTHESIS_LEFT` token in Prism is classified as either `tLPAREN` or `tLPAREN2` in the Parser gem.
The tokens that were previously all classified as `tLPAREN` are now also classified to `tLPAREN2`.

With this change, the following code could be removed from `test/prism/ruby/parser_test.rb`:

```diff
-          when :tLPAREN
-            actual_token[0] = expected_token[0] if expected_token[0] == :tLPAREN2

This PR fixes a token incompatibility between Parser gem and `Prism::Translation::Parser` for left parenthesis.

## Parser gem (Expected)

Returns `tLPAREN2` token:

```console
$ bundle exec ruby -Ilib -rparser/ruby33 \
-ve 'buf = Parser::Source::Buffer.new("example.rb"); buf.source = "foo(:bar)"; p Parser::Ruby33.new.tokenize(buf)[2]'
ruby 3.4.0dev (2024-09-01T11:00:13Z master https://github.com/ruby/prism/commit/eb144ef91e) [x86_64-darwin23]
[[:tIDENTIFIER, ["foo", #<Parser::Source::Range example.rb 0...3>]], [:tLPAREN2, ["(", #<Parser::Source::Range example.rb 3...4>]],
[:tSYMBOL, ["bar", #<Parser::Source::Range example.rb 4...8>]], [:tRPAREN, [")", #<Parser::Source::Range example.rb 8...9>]]]
```

## `Prism::Translation::Parser` (Actual)

Previously, the parser returned `tLPAREN` token when parsing the following:

```console
$ bundle exec ruby -Ilib -rprism -rprism/translation/parser33 -ve \
'buf = Parser::Source::Buffer.new("example.rb"); buf.source = "foo(:bar)"; p Prism::Translation::Parser33.new.tokenize(buf)[2]'
ruby 3.4.0dev (2024-09-01T11:00:13Z master https://github.com/ruby/prism/commit/eb144ef91e) [x86_64-darwin23]
[[:tIDENTIFIER, ["foo", #<Parser::Source::Range example.rb 0...3>]], [:tLPAREN, ["(", #<Parser::Source::Range example.rb 3...4>]],
[:tSYMBOL, ["bar", #<Parser::Source::Range example.rb 4...8>]], [:tRPAREN, [")", #<Parser::Source::Range example.rb 8...9>]]]
```

After the update, the parser now returns `tLPAREN2` token for the same input:

```console
$ bundle exec ruby -Ilib -rprism -rprism/translation/parser33 -ve \
'buf = Parser::Source::Buffer.new("example.rb"); buf.source = "foo(:bar)"; p Prism::Translation::Parser33.new.tokenize(buf)[2]'
ruby 3.4.0dev (2024-09-01T11:00:13Z master https://github.com/ruby/prism/commit/eb144ef91e) [x86_64-darwin23]
[[:tIDENTIFIER, ["foo", #<Parser::Source::Range example.rb 0...3>]], [:tLPAREN2, ["(", #<Parser::Source::Range example.rb 3...4>]],
[:tSYMBOL, ["bar", #<Parser::Source::Range example.rb 4...8>]], [:tRPAREN, [")", #<Parser::Source::Range example.rb 8...9>]]]
```

The `PARENTHESIS_LEFT` token in Prism is classified as either `tLPAREN` or `tLPAREN2` in the Parser gem.
The tokens that were previously all classified as `tLPAREN` are now also classified to `tLPAREN2`.

With this change, the following code could be removed from `test/prism/ruby/parser_test.rb`:

```diff
-          when :tLPAREN
-            actual_token[0] = expected_token[0] if expected_token[0] == :tLPAREN2
```
