Thanks for the PR. Generally, for doc-only changes, there is no need to include a NEWS entry so please update the PR to remove it. Also as was noted elsewhere, in general you should just submit one PR and against the master branch (or whatever the highest applicable branch is). If accepted, the core developer will mark the PR to be automatically backported to appropriate maintenance branches. So I'm going to close the PRs you submitted against other branches so you don't need to update them.

A Python core developer has requested some changes be made to your pull request before we can consider merging it. If you could please address their requests along with any other requests in other reviews from core developers that would be appreciated.

Once you have made the requested changes, please leave a comment on this pull request containing the phrase I have made the requested changes; please review again. I will then notify any core developers who have left a review that you're ready for them to take another look at this pull request.

Thanks. I was not sure what to do and so I decided to write to the previous ones. Sorry for that.
