group id not set in docker-custom/Dockerfile.custom (v1.1.3)

Hi, in docker-custom/Dockerfile.custom no group id is created or assigned to the user node-red. It defaults to the root group. This creates permission problems when running something like,

docker run  --rm  --user=$UID  -it -p 1880:1880 -v /home/user/.node-red:/data  --name mynodered nodered/node-red

as the permissions in the host directory /home/user/.node-red, become mangled.

Adding something like the following seems to address it,

Inizia da docker-custom/Dockerfile.custom e confronta la configurazione dell’utente e del gruppo node-red con il comando docker run segnalato. Verifica che l’immagine assegni node-red al proprio gruppo e che i file montati di /home/user/.node-red non ricevano più i permessi del gruppo root.
