    ci: Explicitly specify Python installation path on Windows
    
    Meson used to try and guess at the Python path. While this worked fine
    for GLib before, it probably didn’t work 100% for other projects, so
    Meson have made it an explicit option.
    
    Set that option with the Python path used on the Windows CI machines.
    
    This fixes a Meson warning with Meson >0.60.
