This change introduces a new playground in the docs where a
user can test out Bandit right within their browser. This
code uses PyScript (and sphinx-pyscript) to generate an editor
window on a sphinx page in our docs. When the user clicks the
play button, it runs Bandit against the example code they have
provided.

If Bandit finds issues it renders them in a box on the same page
under the editable code.

The editor windows by default includes an example of correct and
incorrect usage of ssl context.
