Pywikibot tests fails with Python 3.12. The reason is that itertools.batched() is used instead of the old pywkibot.itertools.itergroups() implementation but batched needs a int value for the group lenght whereas itergroups also works with NoneType as a side effect. As a result _paraminfo.fetch fails.
