codespell: add config and action to codespell the code to avoid known typos

[carsen-stringer]

thanks I did not know about this tool, does this only check in comments / non-code? I am very wary of any tool that can change actual code (which is why we don't use black)

It does check everything, including code. I did have cases of finding/fixing typos in scripts not covered through tests. It doesn't change any code unless you ask it when you run it locally - action just checks

thanks it was helpful to see the typos, but I don't feel comfortable with it being able to change code
