chore(examples): fix router for react and solid basic sandboxes

[SeanCassiere]

Although, the sandboxes for examples/react/basic and examples/solid/basic worked previously, the routes provided to TanStack Router weren't being rendered since the <RouterProvider> wasn't being used. This change fixes that.

Also, solid-js doesn't have className as an available prop, instead it directly uses class instead.

This is being removed since the Panel variant is being used. The same change was made for the Solid variant as well.

When I have some time, I'll add a follow-up PR that actually uses TanStack Query in those sandboxes as well so that we can see its Panel being populated with Queries and Mutations.
