Segmentation fault when running tests with Dask on Github Actions

[NoraLoose]

PR #192 simply changes the documentation while leaving the code base untouched. Still, the tests fail, but only when using dask:

https://github.com/CWorthy-ocean/roms-tools/actions/runs/11824684038/job/32946744730?pr=192

It looks like dask may be consuming too many resources on GitHub Actions, leading to a segmentation fault. Not sure what is going on. The tests with dask pass just fine locally.
