add a mobile preview as well

[oppianmatt]

what a wonderful project. I gave it a try and was amazed. I wanted a mobile view also so I changed Preview.tsx to return 2 iframes like so:

  return (
    <div className="flex">
      <iframe
        title="Preview"
        srcDoc={throttledCode}
        className="border-[4px] border-black rounded-[20px] shadow-lg 
        transform scale-[0.8] origin-top-left w-[400px] h-[832px]"
      ></iframe>
      <iframe
        title="Preview"
        srcDoc={throttledCode}
        className="border-[4px] border-black rounded-[20px] shadow-lg 
        transform scale-[0.8] origin-top-left w-[1280px] h-[832px]"
      ></iframe>
    </div>
  );
}
