[Soundcloud] Charts rework?

[litetex]

Soundcloud recently reworked their charts and e.g. the Top 50 are now missing.

See https://github.com/TeamNewPipe/NewPipeExtractor/pull/1332#issuecomment-3067240438 for further reference.

It looks like they are currently reworking the overall system which should be reflected in the extractor.
