Use YJIT in our Container

[bastelfreak]

Shopify worked on compiler improvements for Ruby: https://github.com/Shopify/yjit This was merged upstream in Ruby 3.1 and got a lot of improvements in Ruby 3.3. We now use 3.3 in our container images so we should check if our application is compatible with the new compiler and use it. Some background information: https://dev.to/colinsoleim/supercharging-rails-enabling-rubys-yjit-compiler-in-production-56o0. The Ruby container we use already has it enabled: https://github.com/docker-library/ruby/blob/77efb18a0fb15955a4f77c9fa1d3968875915b78/3.3/bookworm/Dockerfile#L37-L57
