PEPs API: handle name with commas in CSV author list

[hugovk]

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.

Given any change could inevitably have an impact on any tools out there using this data, which probably handle this anyway, might it not make sense to add a parallel property that is an actual JSON list of authors? This way no additional handling is needed by a client (they're already parsing JSON) and the format remains backward-compatible.

Yes, that sounds sensible.

This will likely need an update to the source PEPs as well:

Author: Barry Warsaw, Jeremy Hylton, David Goodger, Alyssa Coghlan

Author: Fred L. Drake, Jr. <fred@fdrake.net>

PEP 1 defines this as part of a "RFC 2822 style header preamble":

Author: <list of authors' names and optionally, email addrs>
