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
this will allow for retrieving playlist videos as playlistVideoRenderer
which we already have a parser for. another benefit is being able to
list videos in a playlist which have been deleted/made private.
