### Region

Germany

### Example URLs

https://www.zdf.de/serien/northern-lights/begegnung-auf-der-bruecke-100.html

### Provide a description that is worded well enough to be understood

Provide additional metadata for zdf extractor. 

Should be able to get this from this API: https://api.zdf.de/content/documents/zdf/serien/northern-lights/begegnung-auf-der-bruecke-100.json?profile=player-3, output contains this at:

```
/programmeItem/0/http:~1~1zdf.de~1rels~1target/http:~1~1zdf.de~1rels~1cmdm~1series/seriesTitle
/programmeItem/0/http:~1~1zdf.de~1rels~1target/http:~1~1zdf.de~1rels~1cmdm~1season/seasonNumber
/programmeItem/0/http:~1~1zdf.de~1rels~1target/episodeNumber
```


### Provide verbose output that clearly demonstrates the problem

- [X] Run **your** yt-dlp command with **-vU** flag added (`yt-dlp -vU <your command line>`)
- [ ] 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
