It used to not emit this token type, but now it does. So when a newer version of prism is present, we can fall back to the same code that ripper uses. Ref: * ruby/ruby#15914 * ruby/prism#3859

The reason this logic for different methods branches in the class instead of internally was to be eagerly aggressive about runtime performance. This code is currently only used once for the document where it's invoked ~N times (where N is number of lines):
```ruby
module SyntaxSuggest
class CleanDocument
# ...
def join_trailing_slash!
trailing_groups = @document.select(&:trailing_slash?).map do |code_line|
take_while_including(code_line.index..) { |x| x.trailing_slash? }
end
join_groups(trailing_groups)
self
end
```
Since this is not currently a hot-spot I think merging the branches and using a case statement is a reasonable tradeoff and avoids the need to do specific version testing.
An alternative idea was presented in #241 of behavior-based testing for branch logic (which I would prefer), however, calling the code triggered requiring a `DelegateClass` when the `syntax_suggest/api` is being required.

on_spwhen using prism #241 is adding branching logic for different prism versions based on changes to HEAD. I want to guard against regressions. This change adds the ability to test against multiple versions, including HEAD (which is currently failing on main, but passing on their branch).on_spinsyntax_suggestruby#15914on_spwhen using prism #241 to get tests to pass on head.
