PyQt6: Missing QAction.setMenu or equivalent

[Ales Erjavec]

Hi

In Qt6 QAction was moved to QtGui module and is therefore missing
`setMenu(QMenu)`, `menu()` , or rather the methods are implemented as
templates
that will be instantiated only when called
(https://doc.qt.io/qt-6/widgets-changes-qt6.html#qaction-qactiongroup).

How do we set a menu on an QAction in PyQt6 since `QAction.setMenu`
does not exist?

Best wishes
