Use the new sonroyaalmerol/steamcmd-arm64

This image support new architectures such us Raspberry PI 3, 4 and 5
with 16K page size.

Move "core.env" to ".env" so the docker compose file can access to the
enviromental variables.

Set the server port to 27015 (default steam relay port) and expose that
port at the docker compose by using the server port enviromental
variable.

Add default value for DATA_PATH as it was missing if "STEAMAPPDATADIR"
wasn't set.

Look for override .env file at docker compose example so you can
override desired enviromental variable.
