CRI: general grammar/spelling/consistency cleanup
No semantic changes, but a lot of shuffling of docstrings to make things
more consistent. In particular, standardise on the zeroth-article (i.e.
prefer `// Version` to `// The version`) and ending all docstrings with
periods.
(This knowingly conflicts with #36446 and intentionally omits changing the
Annotations field - I'll rebase this or that respectively as necessary.)
