community/snapshot: move from testing and add GNOME Team as maintainers
We are not maintainers of this, so asking for the maintainer for permission:
- To move to community
- To allow
team/gnome
in theMaintainer
line, so that we get notified when things change. Snapshot is now part of GNOME Core, so it would be convenient for us. The current behavior of gitlab and the bot means that we will not be able to approve, so hopefully this is not a big blocker😄
