[REG] Behavior breakage in Qt 6.5: Virtual keyboard style qrc import path changed

In Qt 6.2.3, virtual keyboard styles installed in /QtQuick/VirtualKeyboard/content/styles were treated as built-in styles and imported by default. After the change mentioned at the end, these styles are no longer detected; the import paths seem to have been changed, and the following change had to be made in our application code to get the original behavior back:

-    <qresource prefix="/QtQuick/VirtualKeyboard/content/styles"> 
+    <qresource prefix="/qt/qml/QtQuick/VirtualKeyboard/Styles/">

The commit that introduced this behavior change seems to have been:
