We want to update the exported module of widget-layout to be in-line with what we do in learning-resources: expose a single hook that will render everything given the layout type as a string. As of now, the only layout type will be `landingPage`. See https://github.com/RedHatInsights/chrome-service-backend/blob/main/docs/dashboard-layouts.md#base-layouts and https://github.com/RedHatInsights/learning-resources/blob/master/src/AppEntry.tsx#L4
