Ansiblify prepare-infra-docs-for-afs

The existing code in branch made a directory for build/{{ branch.tag |
dirname }} but then moved things to build/{{ branch.tag | basename }}
which produced:

  html/
  html/feature
  html/zuulv3

Fix that. While we're in there, go ahead and change this into individual
ansible tasks.
