Build and push Docker image on tag

[mvitale1989]

Thank you for this awesome project! This PR adds support for docker image build&publish to the Github image registry, when a tag is pushed.

If e.g. tagging a commit as v1.3.0, this workflow will make the image available as:

• ghcr.io/rhasspy/wyoming-satellite:1.3.0
• ghcr.io/rhasspy/wyoming-satellite:1.3
• ghcr.io/rhasspy/wyoming-satellite:latest

I had built the 1.2.0 image for myself (can be inspected with docker pull ghcr.io/mvitale1989/wyoming-satellite:1.2.0-1, with a slightly different tagging scheme) to use it in my k8s cluster, but it'd be great if this is done in the project repo itself.

The additional dependencies are useful client tools to record/play sound against the most common sound servers.

Did you build one image and use it for all different containers?

If you're referring to my Kubernetes deployment, I only built the wyoming-satellite image. The other containers use other images which were already publicly available (e.g. wyoming-piper, wyoming-whisper and wyoming-openwakeword are all on Docker Hub already)

I improved your work a bit (i hope).
