### Region

_No response_

### Description

yt-dlp always give the meesage "ERROR: Unsupported URL" but sohu is listed as one of the supported sites...

### Verbose log

```shell

Discussion:
The existing sohu extractor looks for a totally different URL pattern which seems to no longer exist. Probably the whole extractor needs to be re-written
I found https://github.com/soimort/you-get works for sohu
that might be helpful
