In #2094 we fix tests that have degraded due to upstream changes. In #2059, we attempted to add daily scheduled runs of CI to catch this sort of thing early, so we wouldn't be interrupted with trying to fix failing tests when merging new code.

The scheduled part is working, but this issue has been present for over a month:
https://github.com/openzim/mwoffliner/actions/runs/10862381298

We need to figure out how to actually get emails when this fails.
