zigbee2mqtt: config goes in data dir (writable), not separate ro mount

Browse source 
z2m migrates configuration.yaml on startup and needs write access.
Remove the separate :ro config mount; rely on the base compose's
/opt/homelab/data/zigbee2mqtt/data:/app/data read-write mount instead.
configuration.yaml must exist at that path on the node before first run.
