ref(insights): remove conditional that render module upsell

[DominikB2014]

Before domain views were released, we conditionally rendered the module upsells. If the domain views were not enabled we rendered full screen module upsells, otherwise we rendered a body upsell (so that the tabs/headers are retained).

Now that we GA'd domain views, we no longer need these conditions.

This PR also removes the Feature component in the ModuleBodyUpsellHook component. Feature gating already handled in the ModulePageProviders, so there's no reason to do it twice.
