feat(routing): add files_sharing_raw to rootUrlApps

- Registers the files_sharing_raw app as a root-URL app so that its routes are served under /raw/{token} and /rss instead of the default /apps/files_sharing_raw/... prefix.
  This is required for the files_sharing_raw app to generate correct canonical raw URLs via PublicUrlBuilder.
