Add note that accessing root user instance uses http://localhost:6911/vnc.html - i.e. port 6911 rather than 6901

Not really a bug but not a feature request either...

I know its obvious once you know it (or look closely/pay attention properly...) but it might help to add the 6911 port URL after the root user run instructions as its a subtle difference and you get the login page but then a 'failed to connect' message if you use the standard URL with 6901, which can be a bit confusing.

Something like this:

    2.1) Using root (user id 0)

    Add the --user flag to your docker run command:

    docker run -it --user 0 -p 6911:6901 consol/rocky-xfce-vnc

    Then use this URL to connect: http://localhost:6911/vnc.html. (note the different port number than default user connection)
