[QGIS-Developer] CI broken (MinGW64)

[Andrea Giudiceandrea]

> Will be fixed with this: https://github.com/qgis/QGIS/pull/45303

Hi Sandro,
probably this is related... while, now, the MinGW64 Windows build 
succeeds, QGIS from the MinGW64 build doesn't run properly and the 
Python support results disabled.

Running a recent QGIS (5a572dac) from MinGW64 Windows build artifact, 
the following error is reported at the beginning and QGIS doesn't have 
the Python support:

Couldn't load SIP module.
Python support will be disabled.

Traceback (most recent call last):
