Alt + keypad codes: docs say the Windows path is unit-tested only; fix two comments

The type parity row no longer says the NumLock-on path was tried on
Windows: neither path has been run on a Windows machine yet. The comment
on the NumLock-off egui keys says Clear comes as the top-row 5, and the
test comment names the keys 0151 and 0234 actually use.
