fix: swap trailing determiners at the end of titles
fixes #9815.\n\n Some files have their , A or , The at the end of the file to prevent alphabetical sorting clustering these titles together. This stops working when searching for files inside radarr as a cleaned title will have 'prestigethe' instead of 'theprestige'.
