Support new React 17 JSX Transforms (runtime: automatic)

See original GitHub issue

React 17 has a new JSX Transform that Next.js 10 has default support for. Other projects, like Emotion 11 also have support.

I don’t believe mdx-js does yet, when I try to build with a .babelrc like:

{
  "presets": [
    [
      "next/babel",
      {
        "preset-react": {
          "runtime": "automatic",
          "importSource": "@emotion/react"
        }
      }
    ]
  ],
  "plugins": ["@emotion/babel-plugin"]
}

@mdx/loader fails with importSource cannot be set when runtime is classic when building. Related StackOverflow issue.

It looks like this may be on the way in v2? I didn’t see an existing issue to track, so opening this.
