Storybook: handle next/image component

[natterstefan]

Feature Request

Make sure next/image works in Storybook as well.

Basic example

• Image component does not work with Storybook vercel/next.js#18393 (comment) (mentioned here)
• Solution: https://storybook.js.org/blog/get-started-with-storybook-and-next-js/

// .storybook/preview.js
import * as NextImage from "next/image";

const OriginalNextImage = NextImage.default;

Object.defineProperty(NextImage, "default", {
  configurable: true,
  value: (props) => <OriginalNextImage {...props} unoptimized />,
});
