Partial followup for #1262

[litetex]

• Fixed Checkstyle (Already merged via Remove unused method in TimeAgoParser #1212)
• Use UncheckedIOException instead of RuntimeException as it's more specific
• Use correct iPhone model in docs
• Documentation has to be done by @Theta-Dev as I didn't write that code and have no deeper insight into this

• I carefully read the contribution guidelines and agree to them.
• I have tested the API against NewPipe.
• I agree to create a pull request for NewPipe as soon as possible to make it compatible with the changed API.

yt-dlp updated the IOS client again: yt-dlp/yt-dlp#12155

I think this should be ported to NewPipeExtractor.
@litetex do you want to include it in this PR?

I think it would be better to have another PR, since this is kind of off-topic and I also can't review my own PRs ;)
