feat(deploy): add Nginx configuration for marketing product pages

- Introduced a new location block in the Nginx configuration to handle requests for marketing product pages under the /suite path.
- Configured proxy settings to forward requests to the specified MAIL_FRONTEND_UPSTREAM, ensuring proper routing for the frontend application.
- Updated resolver and proxy headers to enhance request handling and maintain compatibility with existing services.
