project.config: remove may-push group

It was intended to be safe, but granted a fair few permissions that are at least a little iffy like tagging, and it's very rarely used. Remove it; I'll configure golang-gob-branchers for the relatively common case of creating a branch once the ganpati group finishes being created.
