Add instructions for working with Caddy 2. Some texts are duplicated from the NGINX part (mainly the configuration part, about systemctl).
* Add new Caddy docs to mkdocs.yml
Adds the new Caddy document to the document tree

* Update caddy.md
Corrects the opening link

Link to both, and call the section reverse proxy, instead of NGINX
