Add JSX.Element to styles type in DocumentInitialProps

[dawsonbooth]

Description

Using next.js with React 18 types and styled-components currently results in a type error in the example custom document component concerning the styles element in the object returned from getInitialProps.

Here's the error I was getting: https://app.warp.dev/block/sL438l5fIzdlNZ1NIjAcOD

This is resolved by placing the styles elements in an array instead of side-by-side in a fragment.

Hi, looks like this type should be handled so I updated to leave the example as is and fix the internal type, thanks for looking into this!
