Missing libQt6QmlCore.so.6 in Linux PyQt6-Qt6 wheels

Hi,

With PyQt6 6.9.0 and PyQt6-Qt6 6.9.0 on Linux, importing QtCore from QML 
fails. The wheel includes qml/QtCore/
libqtqmlcoreplugin.so, which depends on libQt6QmlCore.so.6, but that 
library is missing.

On my machine, the loader falls back to the system Qt 6.11 library, 
producing:


libQt6Core.so.6: version 'Qt_6.11' not found
(required by /lib64/libQt6QmlCore.so.6)

Minimal example:

from PyQt6.QtCore import QCoreApplication, QUrl
from PyQt6.QtQml import QQmlEngine, QQmlComponent

app = QCoreApplication([])
engine = QQmlEngine()
component = QQmlComponent(engine)
component.setData(b"import QtCore\nCameraPermission {}", QUrl())

for error in component.errors():
     print(error.toString())

Inspecting the Linux x86_64 wheel for Qt 6.10.2 shows the same omission. 
Could QtQmlCore be missing from PyQt-
builder’s bundled library dependencies?

Thanks!
