/**
* Called after every page Gatsby server renders while building HTML so you can

* Gatsby does a two-pass render for HTML. It loops through your pages first
* rendering only the body and then takes the result body HTML string and
* passes it as the `body` prop to your `html.js` to complete the render.
*
* It's often handy to be able to send custom components to your `html.js`.
* For example, it's a very common pattern for React.js libraries that
* support server rendering to pull out data generated during the render to
* add to your HTML.
*
* Using this API over [`replaceRenderer`](#replaceRenderer) is preferable as
* multiple plugins can implement this API where only one plugin can take
* over server rendering. However, if your plugin requires taking over server
* rendering then that's the one to
