Currently we pass `usePortal={false}` to the `Menu` shown when adding a field to a document view in the crud (and in add a document modal). Let's update it to `usePortal={true}` (the default behavior https://www.mongodb.design/component/menu/example/ ) so that it doesn't get cut off and cause scrolling issues on the page.

We'll want to pass a scroll container ref, maybe something that can be passed through context and a provider.
