Update Python 2 syntax and drop Python-2-only examples.

Fix all Python console prompts to the full ">>> " for correct
highlighting.

Use "pycon" instead of "python" for interactive Python console session.
The "python" lexer is for Python scripts and doesn't interpret the ">>>"
prompt.

Fix all Python console code blocks to more accurately display what the
user will see. For example, when assigning a value to a variable, it
isn't also echoed.

Fix typo ".. code::" → ".. code-block::".

Use "console" instead of "sh" for shell sessions. The "sh" lexer is for
shell scripts. For a complete list of lexers, see:
https://pygments.org/docs/lexers/

Use blacken-docs to run black on code blocks. This is now included as a
pre-commit hook.

They were removed from the code in

* Add code example for `aud` being an array

The previous code example only showed the `aud` claim as a single
case-sensitive string, despite the documentation mentioning that the
`aud` claim can be an array of case-sensitive strings

Add a code block demonstrating the `aud` claim being an array of
case-sensitive strings to make it more clear to the user that it is a
permitted use of the `aud` claim

* Add example of the `audience` param as an iterable

Demonstrate to users reading the documentation that the `audience`
parameter is not restricted to the `string` type, but can also accept an
iterable, as implemented in PR#306

Small typo fix
