Updated Formik testing example, added a missing parameter

[HouCoder]

This PR forgot to add the second onSubmit parameter in the example code, which causes the testing to always fail.

  ● rendering and submitting a basic Formik form

    expect(jest.fn()).toHaveBeenCalledWith(...expected)

    - Expected
    + Received

      {"email": "[email protected]", "firstName": "John", "lastName": "Dee"},
    - Anything,

    Number of calls: 1

For future reference, could you point to forkik documentation for this? I couldn't find it.

[HouCoder]

Do you mean the Formik doc for the onSubmit callback? If so then this is the doc - https://formik.org/docs/api/formik#onsubmit-values-values-formikbag-formikbag--void--promiseany

Thanks.

We just need to revert #692.

You probably don't want to expose the formik bag anyway.
