ci: migrate auto-merge to gh cli

- Simplify permissions by removing specific action permissions
- Update the GitHub token reference in the auto-approve step
- Remove the Auto_Merge_PR job and its associated steps
- Add a step to check out the repository using `actions/checkout@v4`
- Replace the automerge actions with a direct GitHub CLI command to merge pull requests
