Describe the feature you'd like:

As a user of react 18 with NextJS (with app directory), I would like to render async server components

example:
// Page.tsx

const Page = async ({ params, searchParams }: PageProps) => {
    const asyncData = await fetchSomeDataAsynchronously()
    return (<foo {...asyncData} />
}

...
// Page.test.tsx

it('should render', () => {
    render(<Page />)
    expect(screen....).ToBe(....)
})

Extracting server page logic would be an alternative, but I think that would also significantly reduce the purpose of RTL if that were to become an encouraged architectural default.

Current progress, workarounds, and demo
