--- '@backstage/plugin-catalog': patch --- Add `CatalogIndexPage` and `CatalogEntityPage`, two new extensions that replace the existing `Router` component. Add `EntityLayout` to replace `EntityPageLayout`, using children instead of an element property, and allowing for collection of all `RouteRef` mount points used within tabs. Add `EntitySwitch` to be used to select components based on entity data, along with accompanying `isKind`, `isNamespace`, and `isComponentType` filters.
