Christy Perez f298ea7477 Update doc with usage of the scratch image ...

The scratch image used to be a regular image, but as of
commit 8936789919c5c8004f346f44a3452d1521818b60 it is a
special case, and cannot be used with 'docker pull.'

Update this doc to reflect the new behavior and clear up
confusion surrounding this image.
