@jolorunyomi can you rebase? this shouldn't include any other changes besides the two config files - reviews for the config files can proceed

[rlratzel]

I think this is probably fine as-is, but as mentioned in a comment, having the cmake label would be nice.

Also, our recently-updated .github/CODEOWNERS has many more extensions for docs than what's listed here. I don't know if we want docs limited to .md files for labels, but if not then I'd refer to the CODEOWNERS file to see a more exhaustive list.

Let me know what you want to do and I'll re-review, or if you don't feel those changes are appropriate I'll approve this.

@jolorunyomi can you take a look at the updated CODEOWNERS and port over the new docs paths?

[mike-wendt]

@rlratzel are these the paths you would like for the doc label?

@jolorunyomi can you make these changes to the config file for the doc label?

Dropped python-codeowners from review as they were added before the rebase and this PR contains no python code
