Disable submit to repo for new docs
While we wait for Feature: add new documentation (help files) dir... (#437), it would be good to disable/grey out the Submit to repository action in addition to the red banner at the top. I just had a workflow where I did read the banner, told myself I would have to submit a MR once I’m done, downloaded the translated po, proof-read it, uploaded it… then forgot about the banner and tried to push.
