Ubuntu 22.04 VmHosts use Ruby 3.0, and Ubunutu 24.04 use Ruby 3.2, so 3.4 syntax would break either. This was theoretically an issue before, but I'm guessing there were no significant syntax changes between 3.0 and 3.2 that Rubocop's rewriting would break. This commits a rhizome/.rubocop.yml file that inherits the default configuration, and overrides TargetRubyVersion.
