macOS doesn't offer Ruby/Git on default install either. Even the situation during Leopard, people railed about how old the versions Apple distributed (many libraries and binaries were riddled with security vulnerabilities and updated infrequently). Actually, I believe you can install Ruby/Git on Ubuntu install if you toggle Development tools. But anyone doing serious Ruby development will use rvm/docker. Even when Ruby was included in Lion, nobody developing Ruby apps could use the vendor-supplied stuff. I remember this from back in 2008. There were countless blog articles telling you to download Ruby and compile. The situation from a decade ago caused a ton of pain in bootstrapping a developer setup.
