kentcdodds and ryanflorence fix react-dom imports
react-dom does not use named exports and when rollup attempts to bundle
these files it gives the following error:

```
[!] Error: 'render' is not exported by ../../node_modules/react-dom/index.js
https://github.com/rollup/rollup/wiki/Troubleshooting#name-is-not-exported-by-module
node_modules/@reach/alert/es/index.js (19:9)
17:
18: import React from "react";
19: import { render } from "react-dom";
             ^
20: import Component from "@reach/component-component";
21: import VisuallyHidden from "@reach/visually-hidden";
```
