When used with DevContainers the Forwarded Address should be used

[rubensa]

Instead of the 127.0.0.1:3000 URL, when we are using a DevContainer with Docker, the Forwareded Address should be used (the one automatically mapped and shown in the PORTS tab) to open the preview (as the Workbench Browser runs in the host environment, not inside the container).

PS: Not sure if the port is automatically forwarded of if I manually forwarded it... If not automatically forwarded that should be done also (so the Forwarded Address can be used)
