Allow additional containers in the deployment

Would be nice to be able to add any other containers in the pod. For example matter server

Hi @gkaskonas, I think the better option would be to create a separate Helm chart. Although Matter is tightly coupled with Home Assistant, we could say the same about MQTT and zigbee2mqtt, for example. I have added only VSCode as part of this Helm chart because it shares the same data directory, which cannot be easily shared across applications inside Kubernetes.
