ci: Don't build Qt5/QtQuick in CI to improve turnaround times

We've already stated in README that KDDW-QtQuick requires Qt 6.
It still works and we'll add important fixes for legacy users.

But it needs to phase out as it's very difficult to maintain two
sets of .qml files, since we can't ifdef to support 2 Qt versions.
