Remove support for Ruby 3.1 and the aligned JRuby 9.4.

- rubycritic.gemspec: update minimum Ruby version to 3.2
- .rubocop.yml: update target Ruby version to 3.2
- CI: drop Ruby 3.1 and jruby 9.4 (Ruby 3.1)
- bump mdl dependency to 0.15.0, which requires ruby 3.2 at minimum
- bump minitest dependency to 6.0, which requires ruby 3.2 at minimum
  - minitest 6 unbundles minitest-mock, so include that and call it
