KTimeTracker ported to Qt6
Related merge request (still open): pim/ktimetracker!16 (merged)
Should I merge the port MR before this MR can be merged?
Also: should I set "stable_kf5": "kf5" or "trunk_kf5": "kf5" if I'm leaving a kf5 branch with the latest state of KF5 KTimeTracker available? Or is it best if I just leave them as none?
