These new errors were caused by dependency updates; numpy 1:1.24.3-1.fc37 and python-xarray 2023.4.2-2.fc37 are likely involved.

I’m not inclined to put a lot of effort into backporting changes from a more recent version of Pandas. If we want to fix the FTBFS, it may be just to skip these two tests and pretend everything is OK.
