Enable Ngrok in the Dockerfiles

Uncomment ngrok service in docker-compose[.dev, .source].yml. The following code MUST BE uncommented.

     ngrok:
     image: ngrok/ngrok:latest
     restart: always
     command:
         - "start"
         - "--all"
         - "--config"
         - "/etc/ngrok.yml"
     volumes:
         - ./ngrok.yml:/etc/ngrok.yml
     ports:
     - 4040:4040
     network_mode: "host"

That’s all ! After launching the dockers, all requests targeted at REDIRECT_TUNNEL_INGRESS or WEBHOOK_INGRESS are effectively tunneled to your backend server !
