Mark Goddard c9cc6f4064 docs: add variable for current branch
This allows us to include the correct branch when cloning repositories
in documentation.

Method adapted from OpenStack Ansible documentation. A backslash is
added on purpose before repository URLs to bypass highlighting which
makes them less readable (dark text on dark background).
