Through 13.2 until 13.4 there was a while where the implementation
language for the Git Hooks were important as the administrator could use
feature flags go change the behaviour to Ruby. This has since been
removed, so this section of the docs can be removed too.

Make git lfs for push mirrors work to GitHub.com

Closes #250654

See merge request gitlab-org/gitlab!43321

There are two changes required:

* Add an Accept: application/vnd.git-lfs+json header to batch requests
* Support the verify action

Without the former, GitHub (but not GitLab) responds with a 406 HTTP
response to the batch request. With it, GitHub responds with a spec
indicating that `verify` should be used.
