docs(antora): expand local playbook example; add docs source to CI playbook

- antora-playbook-local.example.yml: header with copy/setup steps, sibling clone
  layout, and site.keys comments aligned with main playbook
- antora-playbook.yml: include FoodTruckNerdz/docs.git so start_page docs::
  and the Docs component resolve when building from GitHub Actions
