[3.11] Docs: Fix backtick errors found by sphinx-lint (GH-97998) by CAM-Gerlach · Pull Request #98371 · python/cpython

Originally submitted as #97998 , authored by @hugovk and committed by @ezio-melotti .

This backports the fixes in the PR to the 3.11 branch, fixing merge conflicts, dropping those that don't apply and re-running Sphinx-Lint to catch and fix a few more only present on this branch.

I'll also backport this to 3.10 where possible but without the addition of Sphinx-Lint itself (since it isn't run on that older branch...though perhaps it should be?), and then once that's all merged, follow it up with a PR (that can be backported to 3.11) bumping Sphinx-Lint to the latest version (which includes fixes for some additional false positives).

3.10 backport: #98373
