Add multiplatform deployment

[maslyankov]

Making the GitHub Actions workflow build a multi-platform image would make standalone deployments much easier to achieve as you use the same image url for all platforms. This has been tested by myself and you can see the results bellow.

Workflow: https://github.com/maslyankov/sunsynk/actions/workflows/deploy-multi-mp.yml
Resulting image/package: https://github.com/maslyankov/sunsynk/pkgs/container/hass-addon-sunsynk-multi

This change would also require docs changes, but I will get to that if there is interest to merge it.
I am currently using the build image like this, same can be used on all platforms:

compose.yml

services:
  sunsynk-multi:
    image: ghcr.io/maslyankov/hass-addon-sunsynk-multi:main
    restart: unless-stopped
    volumes:
      - ./site_data/sunsynk/options.yaml:/data/options.yaml
    environment:
      MQTT_HOST: mqtt
      MQTT_PORT: 1883
      MQTT_USERNAME: ${MQTT_USER}
      MQTT_PASSWORD: ${MQTT_PASSWORD}
      S6_KEEP_ENV: 1

I like the idea

Can you deploy both at the same time? (current /{arch} and this proposal?
Is the jq command enough to get the image tag?

[kellerza]

Today we publish the images at

ghcr.io/kellerza/hass-addon-sunsynk-multi/{arch}

Can we publish this multi-arch image at the same time?

ghcr.io/kellerza/hass-addon-sunsynk-multi

In that case we can merge and then update the docs & config.yaml files once builds are successfully published

Yes, I will work on that the following days.

The workflow is not ready to be merged. The above commits do not provide the discussed functionality.

Should I revert? or will you do changes in a new PR

TBH, not sure if reverting will re-open this PR

[maslyankov]

I can do a new PR, just please disable this action so it does not make some mess. 😄
