[YouTube] Podcasts in playlists channel tabs are not extracted

[0Karakurt0]

Checklist

• I am able to reproduce the bug with the latest version given here: CLICK THIS LINK.
• I made sure that there are no existing issues - open or closed - which I could contribute my information to.
• I have read the FAQ and my problem isn't listed.
• I have taken the time to fill in all the required details. I understand that the bug report will be dismissed otherwise.
• This issue contains only one bug.
• I have read and understood the contribution guidelines.

Affected version

0.27.7

Steps to reproduce the bug

1. Go to a channel page.
2. Navigate to a "Playlists" tab.
3. Count and take note of the displayed playlists.
4. Open the same channel and tab on YouTube.
5. The number of playlists is bigger.

Example:
This channel has 13 playlists and only 11 of them are displayed in NewPipe.
This playlist and this one are annotated as "N series" and both fail to show up in NewPipe.

I haven't searched for more examples.

Expected behavior

To see the same playlists available through YouTube

Actual behavior

Some playlists, possibly marked as podcasts, are not included.

Screenshots/Screen recordings

Logs

No response

Affected Android/Custom ROM version

Any

Affected device model

Any

Additional information

It does not affect all channels (Edit: As not all of them have podcasts) , and it does not depend on the size of the playlist as in another issue (#12142)
The only difference is that playlist that fail to show up are marked with "N series" annotation on YouTube instead of "N videos", so, I assume it is some name change in addressing them that NewPipe Exstractor fails to see.
If NewPipe opens the link to that playlist through search or external link, it is processed correctly.
Edit: And that they are podcasts.

PS: just noticed that they are marked with radio symbol and have a comment mentioning podcast, so, that's probably the correct name and differentiation that is the issue. Haven't been using YouTube's official page in quite a while)

After confirmation that this is an issue with podcasts, and, possibly, a clearer wording, I'll make a mirroring issue on NewPipe Extractor repo

Apparently there is another type of lockup view model: LOCKUP_CONTENT_TYPE_PODCAST. The JSON is basically the same as LOCKUP_CONTENT_TYPE_PLAYLIST so our extractor for playlists should easily adapt.
