Updates docker installation with X11 forwarding (#365)

# Description

Although the current docker command still works for headless rendering,
it sometimes generates an error message from carbonite. This change adds
an option to enable X11 forwarding when using the prebuilt docker image,
which fixes the error.

## Type of change
