[Feature] Get network name and node from env vars

Description

When running the node using docker-compose, it would be helpful to get the network name and RPC url from environment variables instead of having to modify docker/docker-compose.yml#L22.

This change would do the trick:

diff --git a/docker/docker-compose.yml b/docker/docker-compose.yml
index c78c2eb21..36e8beba7 100644

Commencez par docker/docker-compose.yml, au niveau de la configuration ethereum vers la ligne 22, et examinez les valeurs par défaut proposées pour les variables d’environnement correspondant au nom du réseau et à l’URL RPC. Validez la configuration Compose et confirmez que les deux variables remplacent leurs valeurs par défaut sans nécessiter de modification du fichier.
