add_text documentation for text wrapping is a little confusing

[dlizotte-uwo]

Minor thing - documentation in add_text says:

        :param text_wrap: Whether or not to wrap text (for long text data chunks). Defaults to
                          ``False``, no wrapping.
        :param text_maxlen: The max length of the text for text wrapping. Defaults to 0.

But in the superclass version in PortalBase that's called, it says:

        :param text_wrap: When non-zero, the maximum number of characters on each line before text
                          is wrapped. (for long text data chunks). Defaults to 0, no wrapping.
        :param text_maxlen: The max length of the text. If non-zero, it will be truncated to this
                            length. Defaults to 0.

Suggest updating the MatrixPortal docs to match the PortalBase docs because I kept trying to use text_wrap = True and it was bad news. 😂
