Update jsdom to support document.createRange

[markocikos]

In several places we are using fragment appending to achieve execution of scripts within appended HTML:

const fragment = document.createRange().createContextualFragment(html);

element.appendChild(fragment);

Jest does not support testing this, throwing error that createRange is not defined.

@wincent analysed this here:

We'll get support for createRange in a future update of jsdom:

• jsdom/jsdom#317
• jsdom/jsdom@30bedcf

It's in v16.0.0.

However, I don't think we can update yet because of performance problems:

When we do update, we'll be able to remove that mock.
