This reverts commit 04228de666.
Anki 25.01 Beta 1 revealed a bunch of regressions with the latest
Qt, and zero reports of improvements from it, so we'll be better off
holding off on it for now, and perhaps reporting the deadkeys issue
to Qt once we've got a proper reproduction process.
* Qt 6.8.1
Bumps minimum glibc to 2.35, and minimum macOS to 12
* Drop generation of Qt5 packaged build
Closes#3615
* Include qt6 requirements in aqt wheel; drop extra deps
* Fix aqt wheels growing over time
This also fixes the Mac bundle using an old Qt version.
Linux held back due to ABI breakage; should be fixed in about a week
when PyQt 6.6.1 comes out. Windows build also fails to run - not sure
if it's the same issue or not.
- Windows was on 6.4 as some users reported slowdowns; we'll need to
confirm whether they have come back in the next build.
- Linux has been held back due to https://bugreports.qt.io/browse/QTBUG-114635
