Docs: Multiple (inconsistent) lists of PSF Code of Conduct Work Group members

[JesseWeinstein]

Summary

The current membership of the PSF CoC WG is listed in two different places:

https://www.python.org/psf/workgroups/ (along with the other workgroups)

and

https://wiki.python.org/psf/ConductWG/Charter#List_of_Participants.2FWho_we_are

The all-workgroups one is currently (slightly) out of date (it doesn't include Jeremy Hylton, who was added to the wiki one on Dec 12, 2024), and (like most of the rest of the content of python.org) it lacks a public commit history, so I'd suggest that it be changed to refer to the wiki page, instead of repeating the list there.
