I made a fork and attempted to contribute using codespaces. I couldn't figure out how to modify the codespace to use the correct version of ruby. Does anyone know how to do this?

$ ruby --version
ruby 3.1.3p185 (2022-11-24 revision 1a6b16756e) [x86_64-linux]

The project requires 2.6.3
And my guess is this is why I get errors when I try to build the website.
