QML singletons error without manually creating qmldir file

when creating qml singleton file, that, isn't recognized propertly in Qt 6.8.0. editor shows warnings, fix for that is manually creating qmldir file. even with that fix, properties inside singleton file isn't seen in intellisense sugestion when you want to use it. before i used Qt 6.7.0 and everything worked right. i tested this only on Windows 10, with Qt Creator 14.0.2, so i cannot say if this bug exists on others systems too.
