Document change to style sheet selectors for enum properties
The change is presumably an unintentional side effect of QVariant and
QMetaType system changes in Qt 6, but it arguably is a good change.
Document it in the porting guide, while evaluating whether (and figure
out how) we want to support integer values as well.
Pick-to: 6.3 6.2
Task-number: QTBUG-99642
