[3.10] Docs: Fix backtick errors found by sphinx-lint (GH-97998) by CAM-Gerlach · Pull Request #98373 · python/cpython

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

This backports the fixes in the PR to the 3.10 branch, fixing merge conflicts, dropping those that don't apply and re-running Sphinx-Lint to catch and fix handful of others only present on this branch. I've also dropped the addition of Sphinx-Lint itself to the CIs on this branch.

Once this is 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).

3.11 backport: #98371
