Enable Contribute page to respond to screen size changes (#232)

* Add clean and serve scripts

* Improve code highlighting on contribute

* Ensure we have the latest prismjs and prism-react-renderer
* Shorten example description to make it easier to read and reduce screen sizes where overflow is required
* Fix JSON5 syntax highlighting
* Specify markdown sytnax highlighting for front matter samples. Markdown front matter highlighting will come to PrismJS in the next version (PrismJS/prism#2634)
* Trim whitespace and newlines from the end of code samples

* Add scrollbars to code examples

Enables the Contribute page to shrink according to screen size

* Allow code examples to be scrollable by keyboard users

* Disable eslint warning for tabIndex on pre element
