Remove feature gates for Repository Languages
The repository languages feature got introduced through: https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/19480. This MR included feature flags to guard against performance regressions, which allowed GitLab to test it on gitlab.com before the customers would be exposed. .com worked out fine, as shown by our internal monitoring tools, which prompts feature gate removal. Given the docs weren't present yet, these were added too.
