Subject: [PATCH] chore: enhance nightly build workflow with Docker support

- Added a new job for building and pushing Docker images to GitHub Container Registry.
- Configured the workflow to run on multiple platforms (linux/amd64 and linux/arm64) for broader compatibility.
- Implemented steps for checking out code, setting up Docker Buildx, logging into the GitHub Container Registry, and generating metadata for Docker images.
- Updated the Docker actions to their latest versions for improved reliability and security.

These changes improve the nightly build process by integrating Docker image management, ensuring a more robust and efficient workflow.
