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 makes it hard to do version checks against this value. The current version checks work because there are so few possible values at the moment.
As an example, PR 3337 introduces new syntax for ruby 3.5 and uses `PM_OPTIONS_VERSION_LATEST` as its version guard. Because what is considered the latest changes every year, it must later be changed to `parser->version == parser->version == PM_OPTIONS_VERSION_CRUBY_3_5 || parser->version == PM_OPTIONS_VERSION_LATEST`, with one extra version each year.
With this change, the PR can instead write `parser->version >= PM_OPTIONS_VERSION_CRUBY_3_5` which is self-explanatory
and works for future versions.

When parent scopes around an eval are forwarding parameters (like
*, **, &, or ...) we need to know that information when we are in
the parser. As such, we need to support passing that information
into the scopes option. In order to do this, unfortunately we need
a bunch of changes.
The scopes option was previously an array of array of strings.
These corresponded to the names of the locals in the parent scopes.
We still support this, but now additionally support passing in a
Prism::Scope instance at each index in the array. This Prism::Scope
class holds both the names of the locals as well as an array of
forwarding parameter names (symbols corresponding to the forwarding
parameters). There is convenience function on the Prism module that
creates a Prism::Scope object using Prism.scope.
In JavaScript, we now additionally support an object much the same
as the Ruby side. In Java, we now have a ParsingOptions.Scope class
that holds that information. In the dump APIs, these objects in all
3 languages will add an additional byte for the forwarding flags in
the middle of the scopes serialization.
All of this is in service of properly parsing the following code:
```ruby
def foo(*) = eval("bar(*)")
```

To make it so that you can pass `freeze: true` to Prism parse
methods and get back a deeply-frozen AST that is Ractor-
shareable.

Fixes [Bug #20730]
Notes:

Add the ability to receive a callback when the parser encounters a
shebang that contains additional switches after the Ruby engine.
This is necessary because some command-line flags may be present
there that will alter the parse.

After finding the "if if" typo, some additional typos identified by running `codespell` are also being corrected:

An explicit `false` is not equivalent to the comment being missing,
because the default can be switched with a runtime flag:
```bash
$ ruby --enable-frozen-string-literal -e 'p "foo".frozen?'
true
```

Because this is a user-facing change, we also need to deal with the
fact that CRuby 3.3.0 was just released.
In order to support workflows that want to parse exactly as CRuby
parses in a specific version, this PR introduces a new option to
the options struct that is "version". This allows you to specify
that you want "3.3.0" parsing.
I'm not sure if this is the correct solution. Another solution is
to just fork and keep around the old branch for security patches.
Or we could keep around a copy of the source files within this
repository as another directory and only update when necessary.
There are a lot of potential solutions here.
Because this change is so small and the check for it is so minimal,
I've decided to go with this enum. If this ends up entirely
cluttering the codebase with version checks, we'll come up with
another solution. But for now this works, so we're going to go in
this direction for a bit until we determine it's no longer working.

Ruby allows for 0 or negative line start, this is often used
with `eval` calls to get a correct offset when prefixing a snippet.
e.g.
```ruby
caller = caller_locations(1, 1).first
class_eval <<~RUBY, caller.path, caller.line - 2
# frozen_string_literal: true
def some_method
#{caller_provided_code_snippet}
end
RUBY
```
