Fix Apache 400 error on percent encoded URLs
As discussed in https://gitlab.com/gitlab-org/gitlab-recipes/merge_requests/47#note_4406048, a leftover [OR]
flag caused Apache to fail silently when percent encoded paths like https://git.example.com/User/example/tree/master/test%20folder were requested.
The flag has been removed; the resulting configuration is confirmed to be working properly on at least two affected GitLab instances.
