The authors field in the API is a comma-separated list:

https://peps.python.org/api/peps.json

For example: "authors": "Barry Warsaw, Jeremy Hylton, David Goodger, Alyssa Coghlan"

However, there's at least one name with a comma: "authors": "Fred L. Drake, Jr."

Let's handle this properly, perhaps using the csv module?

Thanks to @davep for finding this.
