starter template: NotFoundError was encountered on the route with ID "__root__", but a notFoundComponent #6239
Description
Which project does this relate to?
Router
Describe the bug
The starter template has this error, would be good for the starter template to be Warning free in the way it's setup.
bun create @tanstack/start@latest .
bun --bun run dev
[vite] (ssr) page reload src/routes/index.tsx
Warning: A notFoundError was encountered on the route with ID "__root__", but a notFoundComponent option was not configured, nor was a router level defaultNotFoundComponent configured. Consider configuring at least one of these to avoid TanStack Router's overly generic defaultNotFoundComponent (<p>Not Found</p>)
