Gitaly: remove ruby dependencies
Now that gitaly!5497 (merged) has been merged, Gitaly no longer starts up the ruby sidecar upon bootup. This is because we have ported all Ruby RPCs over to Go. We can now remove all Ruby dependencies in the omnibus package for Gitaly.
We will have a separate issue for removing ruby related configuration: #7711 (closed)
