MAINT: fix typos - #27344

I've commented on the ones that should be left alone. The others seem to be correct fixes, spelling-wise, though I haven't verified if any have practical considerations (e.g. if changing a warning message might have consequences for things that try to catch that warning message, etc.), but I doubt there are many of those.

Please don't force-push for PRs like this. It makes it very difficult to keep track of which changes have been reviewed and which still need review.

presuming modifying this file is inconsequential

personally my inclination is to merge this commit which implements solely those fixes from the ticket's shell script

the ticket's ed output could later be revisited and a second pull made

The lint checks need to be fixed before merging.

Since the linting errors are in the deprecated distutils module, I don't think they should be fixed.

Thanks @musvaage .
