distributed 2022.8.0 is breaking xarray tests

[dcherian]

What happened:

Xarray test suite is broken.

E.g. https://github.com/pydata/xarray/runs/7699566983?check_suite_focus=true

I guess a fixture was renamed or removed?

[gw0] linux -- Python 3.10.5 /home/runner/micromamba/envs/xarray-tests/bin/python
file /home/runner/work/xarray/xarray/xarray/tests/test_distributed.py, line 132

This is the test file that's failing
