Update vimiv-qt-git AUR package to reflect Qt6 support

[karlch]

Currently, the vimiv-qt-git AUR package hard depends on (Py)Qt5. This is no longer the case.

Instead, we should require one of PyQt5 / PyQt6, which will pull the corresponding Qt version as dependency in case not installed. In the future, this should extend to PySide6.

In addition, the optional dependencies (qt5-svg and qt5-imageformats) must be extended to Qt6, possibly ensuring consistency?

Needs some checking how others do this.

Probably very hacky? For one similar case, I found an old post.

If we look at qutebrowser, the repo package changed to qt6 dependency as soon as qt6 was supported alongside qt5 (Edit: with the former as default and the latter as fallback).

So I guess it's about priority. You decide which version is the default, and make the AUR package depend on that.

Thanks a lot for your input! 😊

I guess this is the way to go (like qutebrowser), a bit sad that there is nothing along oneof = "python-pyqt5 python-pyqt6".

I think it would make sense to update both AUR packages (git and regular) once the next version is out.
