Add workaround for itms-services link issue

[ronaldoussoren]

python issue 120522

The issue describes how adding "itms-services" to a list in urlparse causes problems when uploading apps to the App Store (when using Python 3.12).

Check what the resolution of the linked issue is, and add a recipe to py2app when the decision in that issue is to document a workaround (as opposed to adding a workaround to the CPython code base).
