Publish the Docker image to GHCR

Problem or motivation

It would be helpful if the project published an official Docker image to GitHub Container Registry (GHCR).

The current docker-compose.yml uses: build: .

This requires cloning the repository and building the image locally. Publishing an image such as ghcr.io/pascalorg/editor would make deployment and updates much easier.

The Compose configuration could then use: image: ghcr.io/pascalorg/editor:latest

Thanks for considering it!

Proposed solution

Publish the Docker image to GHCR, for example: ghcr.io/pascalorg/editor:latest

The Compose configuration could then use: image: ghcr.io/pascalorg/editor:latest

Ideally, images could be published automatically for releases and tagged with both the release version and latest.

Alternatives considered

Continue cloning the repository and building the image locally with build: ., although this makes deployment and updates less convenient.
