[PySide] Important: 5.15.0 wheels (Windows 64bit) replaced

[Cristián Maureira-Fredes]

Hello everyone,

Thank you very much Christoph
to help us identify a last missing file
in the wheels.

A new set of Windows 64bit wheels has been uploaded now,
that solve the problem you raised.

Even if the name of the wheel has a '_2',
it will still be picked up when you write:

pip install pyside2==5.15.0

We encourage everyone to give it a try ;)

Thanks
