fix(drone): enhance SSH configuration for deployment process

- Updated the .drone.yml file to include GIT_SSH_HOST and GIT_SSH_PORT variables for improved SSH handling.
- Refined the SSH key scanning and command execution to ensure compatibility with the specified remote host and port.
- These changes enhance the reliability of the deployment process by ensuring proper SSH configuration and host verification.
