Update docs to use the latest image link

In fedora people, we created a link to the latest image:
https://fedorapeople.org/groups/magnum/fedora-atomic-latest.qcow2.
Currently, this link is pointed to
https://fedorapeople.org/groups/magnum/fedora-23-atomic-20160405.qcow2.
It should be updated when a new image is uploaded. For now,
we need to update our docs to point to the new link.
