fix(menulistitem): Change item container element from p to div (#64740)

`DropdownMenu` items can contain either a string or JSX: 

When passing a label with a `div`, this will cause an error because
`div`s cannot be children of paragraph tags. The label and details
containers don't need to be `p` tags so I switched them to `div`s to
avoid this.
