Add Ruby 3.2

[fpsvogel]

Please complete the following information:

• Name: Ruby
• Version: 3.2
• Release Notes/Changelogs:
  • https://github.com/ruby/ruby/blob/ruby_3_1/NEWS.md
    • Just the highlights: https://rubyreferences.github.io/rubychanges/3.1.html#highlights
  • https://github.com/ruby/ruby/blob/ruby_3_2/NEWS.md
    • Just the highlights: https://rubyreferences.github.io/rubychanges/3.2.html#highlights

Note: The upcoming Ruby 3.3 seems irrelevant to Codewars because it doesn't add any syntax features like 3.1 and 3.2 did.
