[PATCH v2] Rewrite wg-quick.8 in mdoc

[Jason A. Donenfeld]

Hi Stephen,

Thanks for doing this. I appreciate it. I can manually diff the text
to the old one if you insist, but I'd really prefer to see either a
list of what text you changed or having the type setting and the text
change done in separate commits. Alternatively, if you refuse to do
that, I'll manually diff, but I'd rather not if you can remember what
you changed.

If there are any changes to content, rather than just the typesetting,
please make this separate commits.
