doc: use code-block:: none for command examples

The ``.. code-block::`` directive can specify a highlight language for
the body of the directive.  Previously the languages "none" and
"console" were the same, but we're now using "console" for creating
terminal-looking output (rather than doing images of terminal windows)
with a black background and white text.

This PR replaces unintended uses of the "console" highlighting language
with "none".
