`AuroToast.register` is to easily register the element without extra importing
`import "@aurodesignsystem/auro-toast"` will still register this element to <auro-toast>
`import { AuroToast } from '../src/auro-toast.js` wont register this element until `AuroToast.register` gets called

Fixed the typo on Recommended Use and Version Control.
`clement` -> `element`
