docs(docker): Make example ymls raw-viewable and other copyedit fixes

* Move all *.yml files to docs/public/deploying so they can be viewable
  as raw files on the webpage
* Link to those files with "(view raw)"
* Move minimal environment variables to Docker Compose section
* Unheading the Docker Quick Run stuff to prepare deprioritizing them
* Remove redundant Registry column in Image table
* Rename reverse proxy subsections to have software name as first word
