refactor: Update Nginx configuration to enable HTTP/2

This commit updates the Nginx configuration file to enable HTTP/2 by removing the `http2` directive from the `listen` directive and adding a separate `http2` directive. This change ensures that the server supports the latest HTTP/2 protocol, improving performance and security.
