Slovakia

### Provide a description that is worded well enough to be understood

tried downloading livestream from https://www.markiza.sk/live/1-markiza but got greeted with 
`[generic] Extracting URL: https://www.markiza.sk/live/1-markiza
[generic] 1-markiza: Downloading webpage
WARNING: [generic] Falling back on generic information extractor
[generic] 1-markiza: Extracting information
ERROR: Unsupported URL: https://www.markiza.sk/live/1-markiza
`
not sure if issue #5444 is related? or is just live not supported and only archive is ?

### Provide verbose output that clearly demonstrates the problem

- [X] Run **your** yt-dlp command with **-vU** flag added (`yt-dlp -vU <your command line>`)
- [X] If using API, add `'verbose': True` to `YoutubeDL` params instead
- [X] Copy the WHOLE output (starting with `[debug] Command-line config`) and insert it below
