Access control documentation: Remove 2.2.x table

Shortly after 2.2.x was released we added a conversion table between
the old style permissions and the new style permissions.

As this is now quite long ago the table can be removed.

-[NOTE]
-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,
-instead you grant ordinary push permissions to the actual
-receiving reference. In practice this means that you set push permissions
-on `refs/for/refs/heads/<branch>` rather than permissions to upload changes
-on `refs/heads/<branch>`.
