Enhance repository cloning in install script

- Updated the install script to support both SSH and HTTPS cloning methods for the repository, improving flexibility for users with different access configurations.
- Added error handling and informative logging to guide users in case of cloning failures, particularly for private repositories requiring SSH key setup.
- Refactored the cloning logic to attempt SSH first, falling back to HTTPS if necessary, ensuring a smoother installation experience.
