Provide a description that is worded well enough to be understood

Crunchyroll now forces to use the beta website, but yt-dlp can’t find any subtitles other than en-us.

By using https://beta.crunchyroll.com/watch/G8WUN8VKP/the-ruler-of-conspiracy as example.

yt-dlp first checks the URL <API>/cms/v2/BR/M3/crunchyroll/episodes/G8WUN8VKP

Then it fetches the stream data from playback URL in API response.

But looking at where the beta website gets the subtitles list and downloads.

Beta website, get the available streams from endpoint /cms/v2/BR/M3/crunchyroll/videos/GQ9FG10XZ/streams.

The above URL is avaiable at episodes endpoint, at path '__links__'->'streams'

The streams endpoint, has all the streams available for the video, and also, the subtitles, check print:

I hope that was helpful to implement the missing functionality.

Provide verbose output that clearly demonstrates the problem

• Run your yt-dlp command with -vU flag added (yt-dlp -vU <your command line>)
