[CI/CD] Implement GitHub Flow with Pre-Release Branch for Workflow Improvements

[a-mabe]

1. Adopt GitHub Flow with a Pre-Release Branch:
   1. Use feature branches for individual changes.
   2. Introduce a pre-release branch for integration and testing before merging into main.
   3. Create pre-releases from the pre-release branch to enable open testing and gather feedback.
2. Streamline Releases:
   1. Optimize the release pipeline to reduce manual effort and errors.
   2. Ensure clear, consistent versioning and deployment steps.
3. Improve Automated Testing:
   1. Expand test coverage to catch issues earlier.
   2. Refine CI/CD workflows for more reliable builds.

Tasks:

1. Set up the pre-release branch in the GitHub repository.
2. Define guidelines for using feature branches and merging into pre-release.
3. Implement CI/CD updates to create pre-releases from pre-release.
4. Expand and refine automated test cases for changes merged into pre-release.
5. Document the updated Git workflow.
