Update RequireJS to latest version

[nathancarter]

Since 2016, RequireJS has been at version 2.2.0.

As far as I can tell, the Jupyter Notebook will use any version of RequireJS above 2.1.17.

I have updated to the latest version of Jupyter and the notebook, which were released about two years later than RequireJS.

$ jupyter --version
4.4.0
$ jupyter notebook --version
5.5.0

And yet, when I load the notebook and look in the Chrome developer tools at the JavaScript sources that have been loaded, my static/components/requirejs/require.js file states that it is version 2.1.22:

/** vim: et:ts=4:sw=4:sts=4
 * @license RequireJS 2.1.22 Copyright (c) 2010-2015, The Dojo Foundation All Rights Reserved.
 * Available via the MIT or new BSD license.
 * see: http://github.com/jrburke/requirejs for details
 */

This is relevant to me, because I am encountering this RequireJS bug, which was fixed in version 2.1.23 (so close!!).
