fix: remove duplicate createRequire in optimizer

[hi-ogawa]

Description

There is duplicate createRequire in playground/ssr-deps/node_modules/.vite/deps_ssr/chunk-B6b7aAQJ.js due to Rolldown's automatic polyfill and Vite's banner.

import { createRequire } from 'module';const require = createRequire(import.meta.url);
import { createRequire } from "module";

//#region rolldown:runtime
var __getOwnPropNames = Object.getOwnPropertyNames;
var __commonJS = (cb, mod) => function() {
	return mod || (0, cb[__getOwnPropNames(cb)[0]])((mod = { exports: {} }).exports, mod), mod.exports;
};
var __require = /* @__PURE__ */ createRequire(import.meta.url);

//#endregion
export { __commonJS, __require };

Current Vite SSR is tolerating this code vitejs#19617, but this gets surfaced when oxc transform rejected this code #85.

I think the banner is redundant now, so just removing it seems fix it.
