[FFe] Switch gnome-shell to use gnome-bluetooth3

Is the MIR ready to go? If the MIR team is fine with moving gnome-bluetooth3 into main as it is right now, consider this FFe approved - but the deadline for any of this is, let's say, end of the day before Final Freeze.

So yeah, consider it a conditional +1 - if MIR team is +1 and the package goes to main, this is instantly 'Triaged'.

MIR Team approved at today's meeting so I'm setting to Triaged.
