[ruby/prism] Fix a token incompatibility for `Prism::Translation::Parser::Lexer`

This PR fixes a token incompatibility between Parser gem and `Prism::Translation::Parser` for
beginless range:

## Parser gem (Expected)

Returns `tBDOT2` token:

```console
$ bundle exec ruby -Ilib -rparser/ruby33 -ve \
'buf = Parser::Source::Buffer.new("example.rb"); buf.source = "..42"; p Parser::Ruby33.new.tokenize(buf)[2]'
ruby 3.3.0 (2023-12-25 revision https://github.com/ruby/prism/commit/5124f9ac75) [x86_64-darwin22]
[[:tBDOT2, ["..", #<Parser::Source::Range example.rb 0...2>]], [:tINTEGER, [42, #<Parser::Source::Range example.rb 2...4>]]]
```

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

Previously, the parser returned `tDOT2` token when parsing the following:

```console
$ bundle exec ruby -Ilib -rprism -rprism/translation/parser33 -ve \
'buf = Parser::Source::Buffer.new("example.rb"); buf.source = "..42"; p Prism::Translation::Parser33.new.tokenize(buf)[2]'
ruby 3.3.0 (2023-12-25 revision https://github.com/ruby/prism/commit/5124f9ac75) [x86_64-darwin22]
[[:tDOT2, ["..", #<Parser::Source::Range example.rb 0...2>]], [:tINTEGER, [42, #<Parser::Source::Range example.rb 2...4>]]]
```

After the update, the parser now returns `tBDOT2` token for the same input:

```console
$ bundle exec ruby -Ilib -rprism -rprism/translation/parser33 -ve \
'buf = Parser::Source::Buffer.new("example.rb"); buf.source = "..42"; p Prism::Translation::Parser33.new.tokenize(buf)[2]'
ruby 3.3.0 (2023-12-25 revision https://github.com/ruby/prism/commit/5124f9ac75) [x86_64-darwin22]
[[:tBDOT2, ["..", #<Parser::Source::Range example.rb 0...2>]], [:tINTEGER, [42, #<Parser::Source::Range example.rb 2...4>]]]
```

This correction enables the restoration of `endless_range_in_conditional.txt` as a test case.
