Remove react-apollo section

This isn't supported anymore as Apollo removed their component
methods that would allow prepass to convert their Query components
to suspense-like primitives.

-## Examples & Recipes
-
-### Usage with `react-apollo`
-
-Instead of using `react-apollo`'s own `getDataFromTree` function, `react-ssr-prepass`
-can be used instead. For this to work, we will have to write a visitor function
-that knows how to suspend on `react-apollo`'s `Query` component.
-
-Luckily this is quite simple, since all we need to do is call the `fetchData`
-method on the `Query` component's instance.
-
-```js
-ssrPrepass(<App />, (_element, instance) => {
-  if (instance !== undefined && typeof instance.fetchData === 'function') {
-    return instance.fetchData()
-  }
-})
-```
-
-Since we're now calling `fetchData` when it exists, which returns a `Promise`
-already, `ssrPrepass` will suspend on `<Query>` components.
