fix(romm) update romm to support v3.x (#28822)

**Description**
Updated the docs, env variables and removed outdated variables.

Auth is required but the variables for it was removed....setup the admin
user from the web gui.
 
Redis is no longer experimental....romm does have a internal redis
server built in but after looking over the code....an external redis can
still be used so leaving redis bits untouched.
