docs: automarkup: linkify git revs
There aren't a ton of references to commits in the documentation, but
they do exist, and we can use automarkup to linkify them to make them
easier to follow.
Use something like this to find references to commits:
git grep -P 'commit.*[0-9a-f]{8,}' Documentation/
Also fix a few of these to standardize on the exact format that is
already used in changelogs.
