fix(drone): update deployment script for environment variable handling and PM2 commands

- Set the HOME environment variable to /root to prevent path expansion issues for npm and bun.
- Replaced the previous PM2 command handling with direct commands to streamline the application lifecycle management for nuxt4-demo.
- Sourced nvm to ensure the correct Node.js version is used during deployment.

These changes enhance the reliability of the deployment process by improving environment configuration and command execution.
