Draft October 23 Jupyter Security Workshop Agenda

I have started a [draft workshop agenda](https://docs.google.com/document/d/1hl1qe72s1CZc7Z3QOh1apANRi--qkupcnWEyH4VNOiQ) in Google Docs for the full-day Jupyter Security Workshop that is part of the [2023 NSF Cybersecurity Summit](https://www.trustedci.org/2023-cybersecurity-summit). The document is publicly viewable, Security Council members have edit access. Other contributors can be granted access.

For reference, [here is the workshop proposal](https://docs.google.com/document/d/1zu_WcckIzSlmhVERTeo0SoHhIr7lDOCuX7Yw5O6Az48) and the full [Summit program](https://docs.google.com/document/d/e/2PACX-1vS12c-mQLAWgND0sBDfCj_Vyj2j9C73Wx8RMF479DwlUTOGQAYI3IFRKXPaHdv2Ced6HP2WreJQ03L7/pub).

Thank you to anyone who has time to provide feedback!
