It used to work... applying

fixed the issue for me, but then at the end I get

Apparently masterdir/builddir/mnemosyne-2.9/mnemosyne/pyqt_ui/pyuic5 has a carriage return in its shabang (fixed upstream, but there's also a new release, it's now pyuic6)

Fix that and it now complains (it used to work I swear!!!) that
```
./pyuic5 add_cards_dlg.ui > ui_add_cards_dlg.py
Traceback (most recent call last):
  File "/builddir/mnemosyne-2.9/mnemosyne/pyqt_ui/./pyuic5", line 15, in <module>
    from PyQt5 import QtCore
ModuleNotFoundError: No module named 'PyQt5'
```

The newer release uses PyQt6, so anything we do to fix that (nothing difficult, every time I try to build a new tiny patch/dependency is needed) will have to be discarded when we upgrade - it says above you tried 2.10, did anything go wrong? I still have hostdir/binpkgs/mnemosyne/mnemosyne-2.10.1_1.x86_64-musl.xbps, why downgrading to 2.9?
