Running xdrgen will result in the following error, and this PR will fix the issue.

When I run make locally this change doesn't seem to be sufficient at fixing the build and dependency issues. @overcat when you run make does it work for you?

Hi @leighmcculloch, this is because we did not specify the version of the Ruby image in the Makefile, and some dependencies may not be compatible with the latest version of Ruby. Specifying ruby:3.0 can resolve this issue.

If we need to upgrade various dependencies and bump the minimum supported Ruby version, let's do it in another PR.

Ah yes I see what you mean. xdrgen builds with Ruby 3.3, but not 3.4. I'll address that in:
