Prism will be the parser in Ruby 3.3. We need to support 3.0+ so we will have to "dual boot" both parsers.
Todo:
- LexAll to support Prism lex output
- Add tests that exercise both Ripper and prism codepaths on CI
- Handle https://github.com/ruby/prism/issues/1972 in `ripper_errors.rb`
- Update docs to not mention Ripper explicitly
- Consider different/cleaner APIs for separating out Ripper and Prism

The env var DEBUG does not work to produce detailed output. It is SYNTAX_SUGGEST_DEBUG. It was changed as part of the dead_end to syntax_suggest migration for Ruby 3.2

When `tmp/alias` already exists, I'm now getting phantom folders in the directory pointing at older aliases which is distracting/confusing. By checking and removing that alias before symlinking we can prevent this strange behavior (possibly caused by newer Mac OS?).
