'caption' not recognized in code-block directive

[jpsenior]

When using a code-block as such:

.. code-block:: text
    :caption: This is some text
    
     This is example text

rst-lint fails with an error: 'Error in "code-block" directive: unknown option "caption"'

Omitting the caption has no error.

It sounds like caption isn't a built-in directive to reStructuredText and needs to be registered. Please see our "Extension" documentation for the necessary info/methods:
