On Youtube, I can download the CC transcript for a video but the transcript does not contain punctuation. How can I punctuate the transcript automatically?

This is a problem studied in Natural Language Processing (NLP), which is often referred to as punctuation restoreation. There are some deep learning solutions that can achieve this, but they aren't perfect, although they can achieve decent results. You can try using https://github.com/ottokart/punctuator2, which is based on this paper. (you can try it out here).
There's no way to get them from youtube, you'll have to generate them yourself. Google offers a service that generates punctuation for arbitrary text, and from my personal experience, it's more accurate than some competitors, so I would run it through that.
