[FEATURE] Add Sonarr Icon to Letterboxd's TV pages

[airther]

Is your feature request related to a problem? Please describe.

Letterboxd now includes more and more TV series. (This user list -- not mine -- provides some examples https://letterboxd.com/yassinentifi/list/tv-shows/). However, users of this integration are currently only able to include an on-page search icon for Radarr rather than Sonarr.

Describe the solution you'd like

Add an icon to search Sonarr on Letterboxd pages for TV series. If the integration cannot tell the difference between films and TVs listed on letterboxd (since all URLs include the word "film"), perhaps add options to either include a Sonarr icon on every letterboxd page or add the icon for releases whose running time exceeds a threshold (like 150 minutes or 300 minutes or anything else).
