fix: correct Prowlarr capabilities

The current `_get_indexer_from_json()` private method only stores the first character of an indexer's `movieSearchParams`/`tvSearchParams`, resulting in Riven only providing the show/movie name to Prowlarr indexers even if they're able to search by year/season/episode.

This commit fixes the issue by removing the 0-slice from the list comprehension.
