Test failures with Python 3.12.0b2

[hroncok]

Hello. We are mass rebuilding all Fedora 39 packages with Python 3.12.0b2 to align Fedora 39 and Python 3.12.0 final releases.

Our argcomplete package fails to build. The test failure is reproducible on Fedora 37/38 as well, from git, with Python 3.12.0b2, like so:

[argcomplete (develop %)]$ git rev-parse HEAD
