Add redirect for Sorairo Utility

[FichteFoll]

The TV series from 2025 has the same name as the OVA of 2021 and is disambiguated by a "(TV)" suffix sometimes, but this is unreliable and it's is much more likely that the series is accidentally recognized as the OVA. Since the OVA only has one episode, we can redirect all other episodes to the TV series.

(Kitsu doesn't even show the (TV) disambiguator and only has it in the URL: https://kitsu.app/anime/sorairo-utility-tv.)

Thanks for the explanation, but is this necessary?

Sorairo Utility - 01.mkv is going to be ambiguous in any case.

Sorairo Utility - 02.mkv and onwards don't need a redirection because applications already know that the OVA has only 1 episode. Comparing the episode number with total episodes (e.g. 2 <= 1), if available, should be enough to determine that the OVA cannot be a match. This is what Taiga does, for instance.

Trackma does an initial title match first and afterwards performs episode redirects. The title matching logic is not affected by the maximum episode count of the matched show, as far as I'm aware, so it would matter there.

I could double-check this, but having such a redirect wouldn't hurt either way.
