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. https://black.readthedocs.io/en/stable/change_log.html#id38
