qBittorrent ignores the desktop theme after update

[D.Dave]

Install qt6ct and set the theme from there, as suggested by @Strit:

[Stable Update] 2022-01-23 - OpenSearch, Kernels, KDE Software, Cinnamon, Pipewire, Mesa, Gnome, LibreOffice

qBittrorrent switched to using qt6, so install qt6ct and set the theme there.
