dependabot updates the docker image for codespaces
precommit automatically adds a commit to remove end-of-line space
dependabot adds a note: "A newer version of pangeo/base-image exists, but since this PR has been edited by someone other than Dependabot I haven't updated it"
It's a minor issue, but I just noticed that:
https://github.com/xarray-contrib/xarray-tutorial/pull/261
I don't think we need to update this image all that often, maybe once every several months, just flagging it.
