use docker-compose command to use --compatibility

This is required due to following warning:

WARNING: Some services (beacon_node) use the 'deploy' key, which will be ignored.
         Compose does not support 'deploy' configuration - use `docker stack deploy` to deploy to a swarm.

Without it the cpu/mem limits are not applied.

 You can re-create containers on the host using:
 ```
-cd /docker/beacon-node-testnet0-1 && docker-compose up -d --force-recreate
+cd /docker/beacon-node-testnet0-1
+docker-compose --compatibility up -d --force-recreate
 ```
 Which will use the `docker-compose.yml` file in that directory.
