Subject: [PATCH] fix: handle collaboratively authored videos in playlists and
 videos endpoint currently, the videos endpoint returns the video uploader
 name, and not "author1, author2, author3" as is the case for videoRenderer
 and playlistVideoRenderer - this might change in the future in order for the
 endpoints to return the same data
