Add GitHub Actions workflow for building and pushing Docker images

- Created a new workflow file 'build-and-push.yml' to automate the building and pushing of Docker images for API and Streamlit services.
- Configured triggers for pushes to version tags and releases.
- Included steps for logging into Docker Hub, setting up Docker Buildx, and building/pushing images with appropriate tags based on the commit SHA and branch name.
