Ruby

I’d like to propose ydah (https://bugs.ruby-lang.org/users/52290) as a Ruby committer.

He has contributed to parse.y.
His contribution includes applying Lrama’s new feature to parse.y (https://github.com/ruby/ruby/pull/10050), fixing invalid syntax error (https://github.com/ruby/ruby/pull/11850), modification of ripper related codes (https://github.com/ruby/ruby/pull/10602) and so on.
He fixes not only parse.y but also compile.c (https://github.com/ruby/ruby/pull/12275).
He is passionate about making Ruby’s parser better. Then I want to make his contribution easy.

I will be a mentor for him.
