Remove Wiki-related code paths in Ruby sidecar

In a prior MR, all Wiki-related RPCs are removed from Gitaly,
all the corresponding code paths in Ruby are redundant. This
commit targets removing Wiki handlers inside ruby sidecar, Wiki
protobuf definition, and gollum gems. The rugged gem is
intentionally left out for the next MR to reduce the change size.

Issue: https://gitlab.com/gitlab-org/gitaly/-/issues/4513
