refactor(deploy): update deployment workflow for production

- Renamed workflow from "Deploy yourpart (blue-green)" to "Deploy to production" for clarity.
- Removed environment variables for SSH configuration and replaced them with direct references to secrets for improved security.
- Updated SSH connection and deployment script steps to utilize secrets for host, port, and user, enhancing the deployment process.
