- Remove deprecated 3.2 pages (QubesOS/qubes-issues#4936)
- Link directly to domU tool man page sources rather than duplicating
the content into qubes-doc. Reasons:
- Even with the warning, people kept trying to edit the auto-generated
pages.
- The auto-generation script had to be run manually, resulting in
stale pages on the website.
- Duplication content is bad in general.
- The auto-generation script was brittle and broke easily.
- The dom0 pages were already hosted on a separate site, so doing the
same with the domU pages is not much worse.
