doc: inspect.getargspec has been removed in Python 3.11

Fixed by dropping the inspection introduced in cdda48c93676. The 2nd "reporter"
parameter to docutils.languages.get_language has been available since 0.8 more
than 10 years ago.

Reported for Fedora on https://bugzilla.redhat.com/show_bug.cgi?id=2022252#c2 .
