docs(README): refer to minified JS and CSS files, improve general layout (#5494)

Refer to minified versions of the JS and CSS files from `unpkg` and `cdnjs`, and add notes about versions. Remove unnecessary quoting in the README, and clarify the comment about v7 (and later) not having the Google Tracking pixel.

 Thanks to the awesome folks over at [Fastly][fastly], there's a free, CDN hosted version of Video.js that anyone can use. Add these tags to your document's `<head>`:

 ```html
-<link href="//vjs.zencdn.net/7.0/video-js.min.css" rel="stylesheet">
-<script src="//vjs.zencdn.net/7.0/video.min.js"></script>
+<link href="//vjs.zencdn.net/7.2/video-js.min.css" rel="stylesheet">
+<script src="//vjs.zencdn.net/7.2/video.min.js"></script>
 ```

 > For the latest version of video.js and URLs to use, check out the [Getting Started][getting-started] page on our website.

-> Video.js version 7's CDN (and newer) builds does not send any data to Google Analytics.
-> In older versions of Video.js (6 and earlier), in the `vjs.zencdn.net` CDN-hosted versions we include a [stripped down Google Analytics pixel](https://github.com/videojs/cdn/blob/master/src/analytics.js) that tracks a random sampling (currently 1%) of players loaded from the CDN. This allows us to see (roughly) what browsers are in use in the wild, along with other useful metrics such as OS and device. If you'd like to disable analytics, you can simply include the following global before including Video.js via the free CDN:
->
-> ```html
-> <script>window.HELP_IMPROVE_VIDEOJS = false;</script>
-> ```
->
-> Alternatively, you can include Video.js by getting it from [npm](http://videojs.com/getting-started/#download-npm), downloading from [GitHub releases](https://github.com/videojs/video.js/releases) or by including it via [unpkg](https://unpkg.com) or another JavaScript CDN like CDNjs. These releases _do not_ include Google Analytics tracking at all.

 Next, using Video.js is as simple as creating a `<video>` element, but with an additional `data-setup` attribute. At a minimum, this attribute must have a value of `'{}'`, but it can include any Video.js [options][options] - just make sure it contains valid JSON!
