[FEAT]: Document how to use the Docker image published on GHCR

[gmacario]

Description

Now that github/workflows/publish_image.yaml has been pushed to the main branch, Docker images are published on https://github.com/orgs/B-AROL-O/packages?repo_name=FREISA

I would suggest to create a compose.yaml file (1) or at least a HOWTO document which explains how to use those images

Additional Information

(1) According to https://docs.docker.com/compose/intro/compose-application-model/

The default path for a Compose file is compose.yaml (preferred) or compose.yml that is placed in the working directory. Compose also supports docker-compose.yaml and docker-compose.yml for backwards compatibility of earlier versions. If both files exist, Compose prefers the canonical compose.yaml.
