Subject: [PATCH] nixos/gitea: add option to disable registration

Although this can be added to `extraOptions` I figured that it makes
sense to add an option to explicitly promote this feature in our
documentation since most of the self-hosted gitea instances won't be
intended for common use I guess.

Also added a notice that this should be added after the initial deploy
as you have to register yourself using that feature unless the install
wizard is used.
