freecad: remove qt5 version

Qt5 support is was officially reduced by qt [1].

FreeCAD supports both Qt5 and Qt6. While their github
build still uses Qt5, the official flatpak uses Qt6 [2].

Additionally, keeping Qt5 support requires pinning
python to 3.12 or older, as shiboken2 would break.
Currently, this breakage is imminent: #412204 unpinned
python, with the next staging-next merge updating py to 3.13.
