* Remove the example

* Remove Deploy To Now buttons

* Remove remaining buttons

I wrote a [script](https://github.com/j0lv3r4/dependency-version-updater) to update dependencies recursively in `package.json` files, e.g.:

```
$ node index.js --path="./examples" --dependencies="react=^16.7.0,react-dom=^16.7.0"
```

This PR contains the result against the examples folder.

* Add prettier for examples directory

* Fix files

* Fix linting

* Add prettier script in case it has to be ran again

Preferably this installation wouldn't be necessary, but in lieu of a fix...

* docs: don't blow away existing query string

See comments in diff - I ran across this and it took me a while to work out why my client side code worked, but the server didn't. It was because I didn't realise that `.render`'s 3rd arg was the query object, so it was losing the _actual_ query string.

¯\_(ツ)_/¯ I think!
