Add codespell: config, workflow, pre-commit config and make it fix few typos

[yarikoptic]

• I have added a news fragment under changelog.d/ (if the patch affects the end users)

it doesn't so I didn't bother

I see that once in a while commits fixing typos come in. With https://github.com/codespell-project/codespell you could minimize them even further since it would be harder for them to sneak in.

Thanks! Why did you add codespell both as a pre-commit hook and a GH Actions workflow?

[yarikoptic]

just what my https://github.com/yarikoptic/improveit/blob/main/codespellit does since not necessarily people have pre-commit as a service or a workflow ;) I will drop the commit adding github action now.

LGTM, please rebase or merge.

Thanks for suggesting this. Let's hope it will cut some manual effort in the future.
Have you run it on all current files?

Also - is it necessary to exclude the vens nox creates from checking when doing a run on all files?

yes, codespell considers all the applicable (non binary) files AFAIK. There is a commit done via datalad run with annotation on execution

cool, adding .nox to excludes (and something for my codespellit script to look for)

pushed rebased

Still waiting for codespell to support .gitignore files.

[chrysle]

@yarikoptic Could you rebase again, please?

[yarikoptic]

done. Also added to skip .mypy_cache

Thank you! I've taken the liberty to add a merge commit (there've been a lot of merges lately).
