We need to set up CI/CD pipelines to automate the process of building, testing, and pushing Docker images to DockerHub for MyLibrary Front & Backend. The pipeline should include the following steps:

• Build: Automatically build Docker images upon new commits or pull requests.
• Test: Run necessary tests to validate the application before pushing the image.
• Push: Upon successful testing, push the built image to DockerHub with appropriate tagging.
• Trigger Conditions: Define when the pipeline should trigger (e.g., on main branch merges, new releases, or PRs).
• Security Considerations: Ensure secrets (such as DockerHub credentials) are securely managed using GitHub Actions Secrets.
