Changing Upstream Branch from HTTPS to SSH for Existing App Branches

Update your app's remote configuration to enable passwordless Git operations via SSH.

1. Identify App Path: Navigate to the specific app directory using cd apps/[app_name].
2. Check Current Remote: Run git remote -v to confirm the existing HTTPS URL (e.g., https://github.com/user/repo.git).
3. Update Remote URL: Execute git remote set-url origin [ssh_url] using the SSH link copied from the GitHub repository. OR run this command:  git remote add upstream [ssh_url]
4. Verify Change: Run git remote -v again to ensure the origin now displays the SSH format (e.g., git@github.com:user/repo.git). AND run: git remote add origin [ssh_url]
5. Test Connectivity: Perform a git fetch OR git pull to confirm the server successfully authenticates using your SSH key.
