[DOC] Remove extra parameter in docstring with incorrect definition (#…

…5617)


There are two `optimizer`'s called out in the `CNNClassifier` class's
docstring. One of them is incorrect and references `keras.optimzer` when
it should be `keras.optimizers`.

This change removes the incorrect parameter in the docstring.
