CI JOB TOKEN for code push

This change simplifies how the GitLab automation system connects to the code repository. Instead of using a hardcoded, specific repository URL with a custom access token, it now uses a built-in GitLab variable that automatically provides the correct repository URL and removes the need for adding PAT

To grant permission to job tokens generated in your project to push to the project’s repository:

• Select Settings > CI/CD.
• Expand Job token permissions.
• In the Permissions section, select Allow Git push requests to the repository.
