fix: change SeriesSearch to MissingEpisodeSearch for season requests (#…

…711)

This fix changes the behavior of how Overseerr requests series data from Sonarr. Previously, when adding new seasons to a partially available series, Overseerr would initiate a SeriesSearch, causing Sonarr to search for all monitored seasons of the series, including those already available. This behavior is now corrected by executing a MissingEpisodeSearchCommand for the specific seriesId, which aligns with the intended behavior of only searching for and adding the newly requested seasons that are not already available.

Resolves: #710
