We should touch these as little as possible and just pass them along

Ripper translator
* We don't know what `on_*` events might return so we cannot assume it's an Array.

You're supposed to return the first argument.
```rb
# Before
[[:stmts_new], [:rescue_mod, nil, nil], [:stmts_add, nil, nil], [:program, nil]]
# After
[[:stmts_new], [:rescue_mod, "1", "2"], [:stmts_add, nil, "1"], [:program, nil]]
```
The correct result would be:
`[[:rescue_mod, "1", "2"], [:stmts_new], [:stmts_add, nil, "1"], [:program, nil]]`
But the order depends on the prism AST so it seems very difficult to match.

The filter class is a 1:1 copy of ruby.
rdoc has 32 test failures. It seems to expect `on_sp` in some cases to render code as written.

It's public API and trivial to implement.

This is everything that `irb` uses. It works in their test-suite, but there are 20 failures when using the shim that I haven't looked into at all.
`parse` is not used by `irb`. `scan` is, and it's basically `parse` but also including errors. `irb` doesn't seem to care about the errors, so I didn't implement that.

It is for example used by `irb`, `rdoc`, `syntax_suggest`

Ripper exposes Ripper::Lexer:State in its output, which is a bit of a problem. To make this work, I basically copy-pasted the implementation.
I'm unsure if that is acceptable and added a test to make sure that these values never go out of sync.
I don't imagine them changing often, prism maps them 1:1 for its own usage.
This also fixed the shim by accident. `Ripper.lex` went to `Translation::Ripper.lex` when it should have been the original. Removing the need for the original resolves that issue.

Ripper is either not used or loaded where it is actually needed

Mostly not having to list version-specific excludes when testing against ripper/parse.y
Also don't test new syntax additions against the parser gems. The version support
for them may (or may not) be expanded but we shouldn't bother while the ruby version
hasn't even released yet.
(ruby_parser translation is not versioned, so let as is for now)
I also removed excludes that have since been implemented by parse.y

See https://github.com/ruby/ruby/commit/6d81969b475262aba251e99b518181bdf7c5a523
It leaves the old variant around. RuboCop for examples accesses `Prism::Translation::Parser35`
to test against ruby-head. For now I left these simply as an alias

This one has been on my mind for a while now.
Currently, there are only tests against the latest syntax version.
This changes the snapshot structure as follows:
* Snapshots at their current location are tested against all syntax versions
* Snapshots inside a version folder like "3.3" are tested against all versions starting from that version
* Snapshots inside a version folder like "3.3-4.2" are tested against all versions in the given range.
This makes sure that as new syntax is added, older versions still work as expected.
I also added a few tests for now valid syntax that should be invalid in older versions (and the other way around as well)
These tests run really fast. So even though it does 3x the work for these, I am still able to run the whole test suite in just 11 seconds.

The added code samples align with `parse.y`, except for `foo(bar baz do end)` which `parse.y` currently rejects but shouldn't.

This was a limitation of parse.y that prism intentionally replicated.

Mostly around newlines and line continuation.
* percent arrays need special backslash handling in the ast
* Fix offset issue for heredocs with many line continuations (used wrong variable as index access)
* More refined rules on when to simplify string tokens
* Handle line continuations in squiggly heredocs
* Correctly dedent squiggly heredocs with interpolation
* Consider `':foo:` and `%s[foo]` to not be interpolation

Slightly tweaking the import script becaues of backtrace format changes in Ruby 3.4
Most tests pass in all parsers, with only a handful of failures overall
