vlc-debian-unstable: install `qml6-module-qtquick-effects` instead of `qml6-module-qt5compat-graphicaleffects`
We intend to use QtQuick.Effects
instead of Qt5Compat.GraphicalEffects
when Qt version is at least 6.5.0. Because runtime modules are checked during configuration, vlc!6267 (merged) can not proceed.
