Zigbee2mqtt: Docker test image based on Gladys v4

Yes, the containers are now called:

  • gladys-zigbee2mqqt
  • gladys-zigbee2mqqt-mqtt

Be careful to clean up the containers (in the previous command, I suggested creating the container to test with the name gladys-zigbee2mqqt and this can conflict with the new containers… I rewrote the command with the name gladys-dev-zigbee2mqtt)
