Access control documentation: Linkify conversion table

This patch adds links to the respective categories referenced in the
2.1.x -> 2.2.x conversion table, hopefully making it more usable when
trying to learn the new permission model.

Also; Push Tag +3 never existed in 2.1.x, it is now replaced in the
table with the old actual way to do it.

 In Gerrit 2.2.x, the way to set permissions for upload has changed entirely.
 To upload a change for review is no longer a separate permission type,
