Add kompare and krename to krusader

Depends listed are needed, not options, make sure to read what the app itself does: https://invent.kde.org/utilities/krusader/-/blob/master/krusader/krslots.cpp#L193 It does warn already for you to choose a diff option, same for krename.

Since the last 7 years, KaOS always included everything, since avoiding optdepends is part of the philosophy. I didn't knew that changed yet, while I guess it does so only for apps who show you, what else you can add.

Make sure you actually understand what you are asking. Kompare is part of the default install, but has never been a depend (hard) of dolphin, so anyone is free to remove kompare and use kdiff3 instead. You are asking now to force your preference on all users by making kompare a hard depend of krusader, leaving them no option to remove it and use another they might prefer instead. Seems again an issue of you choosing to do a minimal install, then complaining packages you want are not part of you're install (again, kompare is part of a normal install, so you not having it means you choose to remove it).
