This new service is supposed to comment on new opened MRs which modify an APKBUILD maintained by a team
Implements alpine/tsc#46 (closed) by allowing maintainer lines of the form:
# Maintainer: team/gnome <ablocorrea@hotmail.com>. Thus, the email reflects the main maintainer of the package, which will be assigned the issue, while the user name reflects that the package is part of a team effort, and the team is in consequence pinged.
This additionally includes some small refactoring to reuse code and fix the migration of the repo.
@kdaudt I suppose?
