Helm chart - Ingress notes

[jlpedrosa]

Add notes about ingress + websockets:

# -- Ingress configuration. Zigbee2mqtt does use webssockets, which is not part of the Ingress standart settings.
# most of the popular ingresses supports them through annotations. Please check https://www.zigbee2mqtt.io/guide/installation/08_kubernetes.html
# for examples.

@Koenkk I have been banging my head against the wall with this for a long time. helm-releaser does not support it append the chart to an existing release. I created a patch to fix it upstream. They don't seem to be reviewing PR at all: helm/chart-releaser#407
Options:

• Have the two tags in this repo.
• Wait for upstream to fix it (we can grow old waiting IMO)
• Move the chart to another repo.
• Do a lot of code to release here in the same repo.
• Stop software engineering and open a bar in the bermudas.
