Katello.org pointing at old Katello docs

Ohai (esp @mcorr and @katello),

today I noticed that katello.org still points at Foreman :: Plugin documentation index which has an outdated list of supported content types and doesn’t even list the new Katello 4.1 release.

Given this page is also linked from Foreman :: Plugin Manuals, we probably should clean it up a bit, and point at docs.theforeman.org for documentation?

Thank you.
On my list for this week.
