Subject: [PATCH 1/3] feat: Add Dockerfile and CI build step

Adds a Dockerfile to containerize the sbg.py application.
The Dockerfile uses a Python 3.11-slim base image, installs git
and Python dependencies from requirements.txt.

The GitHub Actions CI workflow has been updated to include a new
step that builds the Docker image using the created Dockerfile.
This ensures the Docker image can be built successfully as part
of the CI pipeline.

Subject: [PATCH 2/3] I've updated the GitHub Actions CI workflow to ensure the
 Docker image is built only once.

I introduced a new 'docker_build' job that depends on the successful completion of the 'build' job (test matrix). I then moved the Docker build step from the 'build' job to this new 'docker_build' job. This addresses your feedback to prevent building the Docker image for each Python version in the test matrix.

Subject: [PATCH 3/3] Optimize Dockerfile apt-get for smaller image size

Updates the Dockerfile to improve the apt-get command used for
installing git.

The changes include:
- Combining 'apt-get update' and 'apt-get install' into a single RUN layer.
- Adding the '--no-install-recommends' flag to 'apt-get install'
  to avoid installing unnecessary packages.
- Cleaning up apt cache and lists ('rm -rf /var/lib/apt/lists/*')
  after installation.

These optimizations help reduce the final Docker image size.
