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 https://github.com/ruby/prism/commit/e5a0221c37
