Migrate from DockerHub to GitHub Packages for future releases

[arnaudlh]

Description

Migrate the rover Docker container distribution from DockerHub to GitHub Packages for future releases. This will centralize our container registry with our source code repository and provide better integration with GitHub workflows.

Benefits

• Centralized distribution: Keep container images alongside source code
• Better CI/CD integration: Seamless integration with GitHub Actions
• Access control: Leverage GitHub's permission system for container access
• Cost optimization: Reduce dependency on external registries
• Enhanced security: Better vulnerability scanning and security features

Tasks

• Set up GitHub Packages container registry for the repository
• Update CI/CD workflows to build and push to GitHub Packages
• Update documentation to reference new registry location
• Ensure backward compatibility during transition period
• Test container pull from GitHub Packages
• Update deployment scripts and references
• Communicate migration timeline to users

Acceptance Criteria

• New releases are published to GitHub Packages
• CI/CD pipeline successfully builds and pushes to GitHub Packages
• Documentation is updated with new registry URLs
• Existing users can still access containers during transition

Additional Context

This migration will improve our development workflow and align with GitHub's ecosystem. We should ensure proper versioning and tagging strategies are maintained during the migration.
