auth docs: set catalog member to primary

[wjgauthier]

Short description

In the example about assigning members to a producer zone, the example.com zone should have its kind (type) set to primary, as native zones are not included in the catalog.

pdnsutil set-catalog does not change the type to primary, so we also have to run pdnsutil set-kind.
