Fix python-heatclient docs publishing

heatclient was only publishing docs in release pipeline but used the
wrong macro - use the proper template for it so that publishing works.

If publishing happens only in release pipepline, the tags-only jobs
(used by client publish template) needs to be used to have content at
top-level as well.
