Switch to yt-dlp from youtube-dl

[jmintb]

Addresses: #56

./start_kit/video_downloader.py was not working with some youtube
videos, due to youtube-dl out of date.

Therefore this commit updates ./start_kit/video_downloader.py to use yt-dlp which is
a more up to date fork of youtube-dl.

It looks like youtube-dl is under new maintenance and may become
viable in the future. Therefore the youtube_downloader variable can be
changes in ./start_kit/video_downloader.py to easily switch between the two.

Relevant github issue for youtube-dl status: ytdl-org/youtube-dl#30568

I have marked this as a draft because I am running ./start_kit/video_downloader.py locally to verify the changes, but it is fine to review.

It seems to work well, I haven't tested all of the videos but it could download youtube videos just fine. 🥳
