Comment typo fixes only (no code changes) in Python/ (no LLM used)

[willy-b]

Just finding and fixing some typos in the code comments (no effect on behavior, no actual code changes in this PR) while taking time to study the codebase. Note there are a couple of other such typos not included here that are already in the pending-review PR #157879 .

Thanks so much to the Python team for the excellent language, community, and tool ecosystem, hopefully these typos are useful to fix.

(This will show failing checks until a team-member adds the "skip news" and "skip issue" labels, which I think should be appropriate for a typo only PR per

cpython/.github/PULL_REQUEST_TEMPLATE.md

Line 15 in 0ec3aee

Most PRs will require an issue number. Trivial changes, like fixing a typo, do not need an issue.

, but don't have permission to add, thanks!)

Nons of those typos are user facing so we do not accept them in general, sorry.
