Fix dependencies in KDE Connect blueprint
The KDE Connect blueprint is apparently a bit stale and was missing a couple of dependencies.
- KF*PulseAudioQt is missing. This is not a recent dependency, but is only applicable on systems with Pulse, where the team does not use Craft. Given nobody cares that I know of, I've just disabled that for this build.
- QtBluetooth, part of QtConnectivity, was missing. This was recently added as a by-default requirement: network/kdeconnect-kde!600 (merged)
- KStatusNotifierItem has been used for awhile, but only "exposed" if built under Qt6, which we do not yet do: network/kdeconnect-kde!589 (merged)
