nixos/gitea: Move to lib.getExe

This makes it so that alternative packages, such as `pkgs.forgejo` are
able to be used instead of the default `pkgs.gitea`.

Also adds myself as a maintainer of the module.

The varible `gitea`, which was used instead of `cfg.package`, has been
replaced with the variable `exe`, and is instead the value of the main
executable, as gotten from `lib.getExe`. `cfg.package` is used when this
value is not appropriate.
