Docs: Examples of templates need more assistance about AMI IDs

* Several places where AMI IDs are used now have more explanation about
   where to find information about them, or links to the builder docs
 * IDs present in examples have not been changed to valid ones, since
   this would be an on-going problem to maintain a current valid ID
 * See github.com issue #3132
