doc: reset the default sphinx literal block format

Set the default literal block format for Sphinx docs
to 'none' instead of the implicit default of 'python'.

This means that default :: blocks won't have any
highlighting applied. Explicit highlighting via
the code-block:: directive is already available and
in use in the docs.
