feat: Remove gitalyruby SLI
Only a handful of methods are still in gitaly ruby, making it a very low traffic and noisy SLI.
The goserver SLI still includes these methods as well. This is called before gitaly-go delegates to gitaly-ruby. This means we will not be missing any grpc methods in our goserver SLI.
As discussed in gitlab-org/gitaly#4186 (comment 1055224814)
