fix: update backup script for better directory handling

- Change TEMP_DIR to use a more structured temporary path
- Adjust rsync command to reflect the new directory structure
- Improve MSG_TEXT formatting for better clarity
- Add 'jq' to the dependencies for JSON processing

These changes address issues with the previous temporary directory location and enhance the output messages for a more informative backup success notification.
