Repair or drop the links to the documentation from the updater
Originally created by @intrigeri on #6445 (Redmine)
Probably due to the privsep steps we’ve taken, the links from the zenity windows run by the updater don’t open at all. We should either find a way to fix them, or find a way to drop them.
The best long-term path might be to make the whole updater frontend a Perl/Gtk application, with embedded documentation when needed, but if we can find a shortcut for the shorter term, it would be good.
