python: reformat with black-23.7.0-2.fc39.noarch

The base image for the "check-tree" test got bumped to Fedora 39.  This
brings a new python-black version (23.7.0 vs. 22.8.0) and requires
reformatting.

Maybe we should stick to 22.8.0, via `pip install`. But it seems better
to just follow the latest black version (the one from current Fedora).

So do the reformatting instead.
