mathtex-script: Use html 'defer' attribute (#2069)

Browse Source 
* Use html 'defer' attribute

Instead of putting the extension script tag at the bottom, we can use the `defer` attribute to execute the script after all other content is loaded.  It has [very good](https://caniuse.com/#feat=script-defer) browser support.

* fix checksums

* use sha384 hashes

* update to Katex 0.11.1

@@ -9,27 +9,27 @@ This extension isn't part of KaTeX proper, so the script should be separately
included in the page, in addition to KaTeX.
Load the extension by adding the following line to your HTML file.
This extension should be loaded *after* all `script type=math/tex` blocks that you want to render.
```html
<script src="https://cdn.jsdelivr.net/npm/katex@0.11.1/dist/contrib/mathtex-script-type.min.js" integrity="sha384-LJ2FmexL77rmGm6SIpxq7y+XA6bkLzGZEgCywzKOZG/ws4va9fUVu2neMjvc3zdv"></script>
<script defer src="https://cdn.jsdelivr.net/npm/katex@0.11.1/dist/contrib/mathtex-script-type.min.js" integrity="sha384-LJ2FmexL77rmGm6SIpxq7y+XA6bkLzGZEgCywzKOZG/ws4va9fUVu2neMjvc3zdv" crossorigin="anonymous"></script>
```
You can download the script and use it locally, or from a local KaTeX installation instead.
For example, in the following simple page, we first load KaTeX as usual.
Then, in the body, we use a `math/tex` script to typeset the equation `x+\sqrt{1-x^2}`.
After we're done writing `math/tex` scripts, we load this extension.
