Ruby support

[ahumenberger]

We want to add language support for Ruby.

• [x] Install Ruby in Docker containers
• [x] Introduce Ruby as a new language
• [x] Register the Ruby language #327
• [x] Implement the ExecuteTests method in the Ruby language #327
• [x] Implement write-tests task
  • [x] Create "plain" repository for Ruby
  • [x] Translate the light repository using a LLM
  • [x] Support Ruby in symflower test
• [x] Implement code_repair task
  • [x] Translate the mistakes repository using a LLM
  • [x] Implement the Mistakes method in the Ruby language
  • [x] Add missing tests #327
• [x] Implement transpile task
  • The transpile repository used examples from the light repository, so no need to translate them again
  • [x] Change the way we get the origin/destination languages for transpilation
    • [x] The transpile package names must be e.g. for Go transpile-java, transpile-ruby, instead of just transpile so it is clear which language we are transpiling from
  • [x] Add missing tests #327
• [x] Documentation
  • [x] Update documentation with new Ruby support #327
  • [x] New features #327
    • [x] Supported providers
    • [x] New Reward points
• [x] Merge fixes #327
