Promise Toast missing documented functionality

[HollaG]

Subject

Toast

Description

Currently, the only example given in the documentation doesn't show how to use the result of the resolved promise in the Toast.

However, looking in https://github.com/marek-sed/chakra-ui/blob/fec70fbab9a548d0644c8da6b8e629b9ccc62f87/packages/toast/test/use-toast.test.tsx#L95, it can be seen that there are callback functions that can be passed in success and error, and not just the options object.
