Publish versioned docker images to dockerhub or ghcr.

Is your feature request related to a problem? Please describe.
Currently users need to build the image themselves which can lead to them building a version and then being out-of-date in a few months.

Describe the solution you'd like
I would like to have the ability to pull a versioned docker image from ghcr, dockerhub or quay to be able to more easily deploy the application as well as being able to get automatic notifications from Renovate if a new version is available.

The versioning could look something like:

• mathman05/fermi:GIT_SHA
• mathman05/fermi:v1.0.15
• mathman05/fermi:latest

where you're able to pull both development releases / per-commit versions as well as tagged versions/releases as well as a "latest" version which always points to the latest version of the image.

Describe alternatives you've considered
Running my own script that periodically pulls down the main branch and builds the latest commit and push it to dockerhub. This is possible however feels weird to me since users usually just want to pull down the image from a trusted dockerhub publisher e.g. linuxserver or the original creator.

I don't know how to make a docker. I wouldn't mind having a docker image for people to use, just someone is gonna need to do this.

this looks to cover how to set it up: https://medium.com/devopsturkiye/pushing-docker-images-to-githubs-registry-manual-and-automated-methods-19cce3544eb1

for anyone interested, i just finished setting up fermi in my ci/cd pipeline to build amd64 images. i’ll take it down once there’s an official build.

https://hub.docker.com/r/takalele/fermi

fermi:
    image: takalele/fermi:latest
    networks:
      - spacebar-network
    volumes:
      - ./fermi/uptime.json:/exec/uptime.json
    ports:
      - 8080:8080
    restart: unless-stopped
