Although rendering properly on Github, the line "--device=/dev/dri:/dev/dri" is not valid markdown and is not rendered correctly on the linuxserver.io site: see https://docs.linuxserver.io/images/docker-plex#intel (the formatting is all messed up).
This fixes the markdown.
* adding multi arch logic and pipeline, first version of included hardware accel info, pulling debs from new endpoint
* removing web screenshotting from ci process
* adding update logic for arm variants and templating readme file
* Adding nvidia environment variables
* Adding information on nvidia container runtime
* updating pipeline logic to use static endpoint and disabling updates on those branches
* bug bashing escape characters in jenkins logic
* remove avahi service that is no longer needed by plex
* set new artifact download location
