🟠 Test failure on master

[max-sixty]

What happened:

We have a failure related to a dask release, I think. Here's a job that failed: https://github.com/pydata/xarray/pull/5365/checks?check_run_id=2757459587

It's the test: xarray/tests/test_computation.py::test_vectorize_dask_dtype_meta

Should we xfail this? Does anyone have thoughts for a quick fix?

this is part of #5366, but nobody noticed since there are a few others we also have to fix. Let's keep this one open as a dedicated issue, though.
