Current behavior: If a file page contains no machine-readable attribution information, media viewer includes only a link to the project (e.g. Wikipedia itself) in the embed link.
Expected behavior: Media Viewer should provide best-available attribution information in the embed link. Since we don't know if the file requires attribution and cannot predictably extract the author, linking to the File: page is likely the best-available information.
