Update TMDbClientTvShows.cs

Changes for jellyfin#381 and jellyfin#382. 

This change updates GetTvShowChangesAsync to:
1) (jellyfin#381) Changes returned type from Task<ChangesContainer> to Task<IList<Change>> to be consistent with GetTvSeasonChangesAsync, GetTvEpisodeChangesAsync, and GetMovieChangeAsync.
2) (jellyfin#382) Add missing startDate, endDate, and page parms
