Updates Flash Messaging Bus doc for react-hot-toast

[cannikin]

To be merged once redwoodjs/redwood#1856 is released

Thanks @jtoar!

Did we merge @Tobbe's suggestion of just exporting * from react-hot-toast? In that case we need to update these import statements to use toast as the default:

import toast, { Toaster } from '@redwoodjs/web/toast'

@cannikin I merged this since the release is out. I don't have an answer about exporting all the things ¯_(ツ)_/¯

TL;DR: The doc is correct 👍

We have this

export { default as toast } from 'react-hot-toast'
export * from 'react-hot-toast'

So the import should be like this, which is what we have here

import { toast, Toaster } from '@redwoodjs/web/toast'
