v4.9.0: Missing ruby_parser dependency

[Mourinto]

Issue

Flog v4.9.0 switched from ruby_parser to prism but removed ruby_parser
as a dependency. However, prism/translation/ruby_parser still requires it.

Steps to Reproduce

1. Install only flog v4.9.0 (without ruby_parser)
2. Run any flog command
3. Get error: "Unable to load ruby_parser"

Expected

ruby_parser should be listed as a dependency in the gemspec

Solution

Add ruby_parser back to dependencies, or switch to pure prism without
the ruby_parser compatibility layer.

I pushed a fix here:

Dupe of #81

OMG My coffee hasn't kicked in. Totally not a dupe.

I'm trying to get ruby/prism#3800 in so I can truly divorce this project from ruby_parser but in the meantime I'mma have to add it back. Le sigh.

I believe all fixes needed are now in prism. Please update flog to confirm. Thanks!
