feat(workflows): add Docker CI/CD for Forgejo, refine Docker Hub flow

Introduced a new CI/CD workflow specifically for building and pushing Docker images to the Forgejo Docker Registry, triggered by pushes to the 'docker' branch. This addition aims to streamline Docker image management and deployment within Forgejo's infrastructure, ensuring a more isolated and secure handling of images. Concurrently, the existing workflow for Docker Hub has been refined to clarify its purpose: it is now explicitly focused on pushing to Docker Hub, removing the overlap with Forgejo Docker Registry operations. This delineation enhances the clarity of our CI/CD processes and ensures a cleaner separation of concerns between public and internal image repositories.
