catalog: export CatalogIndexPage from alpha entry point

Export NfsDefaultCatalogPage as CatalogIndexPage from the ./alpha entry
point along with CatalogIndexPageProps, CatalogTableRow, and
CatalogTableColumnsFunc. This allows adopters to use and customize the
catalog index page within a PageBlueprint in the new frontend system.

No changes to the stable main entry point API.

+Exported the NFS variant of the catalog index page as `CatalogIndexPage` from the `./alpha` entry point, along with supporting types `CatalogIndexPageProps`, `CatalogTableRow`, and `CatalogTableColumnsFunc`. This allows adopters to use and customize the catalog index page within a `PageBlueprint` in the new frontend system.
