* Docs refactor as outlined in https://github.com/ansible/proposals/issues/79. Moves content into 'guides'; refactors TOC; fixes CSS; design tweaks to layout and CSS; fixes generated plugin, CLI and module docs to fix links accodingly; more.
* Adding extra blank line for shippable
* Revise and link inline to the lists of modules
* Fix jinja2 objects.inv fallback path
* Fix bolding of deprecation marker
* Change module_support to link to lists via :doc:
That links to the top of the page instead of a section.
* Add a short text for each list of maintained modules
* Change maintenance info to only display on core and network modules
In case we build docs offline, we want to have a cached copy of the
documentation refs that are in the intersphinx docs we reference.
Update those to the lattest versions from their respective upstreams
This setting allows us to reference jinja2 and python stdlib docs
via docutils refs instead of hardcoding urls.
Fixes#18039
