Removes auto devops callout from repo editor view

See merge request gitlab-org/gitlab-ce!14616

The Redcarpet library is not thread-safe as described in
https://github.com/vmg/redcarpet/issues/570. Since we instantiate
the Redcarpet renderer in a class variable, multiple Sidekiq threads
can access the work buffer and corrupt the state. We work around
this issue by memoizing the renderer on a thread basis.

Closes #36637

Updates to Helm chart docs

Closes #38616

See merge request gitlab-org/gitlab-ce!14589

`Repository#has_visible_content?` used to rely on the cached count of local branches, but
since it is now an independently cached value it needs to be invalidated on its own.
