Fix regular captions

This removes all of the code that was previously used to get them from
/timedtext, and instead, always uses whatever is extracted from the
video page.

This does unfortunately now require a whole video fetch just for the
captions. But assuming captions are only requested by a frontend, this
won't be a problem due to the memory cache. The captions link will be
in memory because the just-requested video is in memory too.

Do not extract storyboards into v/a formats

Fix recommended videos extraction on some remaining IDs

Example: https://www.youtube.com/watch?v=-_GDl6cBebQ
https://github.com/yt-dlp/yt-dlp/blob/2e9a445bc34e79182f900909d727ba87f8487522/yt_dlp/extractor/common.py#L816

Extract fact check notices to second__clarification

Fix recommended extraction when fact check notice

Fix recommended videos extraction on IDs starting with - and _

Let's just leverage yt_dlp instead of rolling our own algorithms and fix
this kind of issue (not finding yt_dlp dump file for a given video) once
and for all

Example videos:

Add many venv names to gitignore

Retrieve the first 20 comments of a video on /api/v1/comments/:videoid

Got some inspiration from https://github.com/nlitsme/youtube_tool (for the x-youtube-client-X
headers).
This is not a complete reimplementation of Invidious API as continuation is not implemented
(to retrieve more than the first 20 comments and comments replies), likes and replies count
are also missing.
