Remove support for Ruby 3.1 and the aligned JRuby 9.4, add support for JRuby 10

- rubycritic.gemspec: update minimum Ruby version to 3.2
- .rubocop.yml: update target Ruby version to 3.2
- CI: drop Ruby 3.1, and change jruby from 9.4 (Ruby 3.1) to jruby to 10 (Ruby 3.4)
- add platform value to the gemspec, and require jar-dependencies version
