[Python-ideas] 2 more admins for the list

FYI both Ethan Furman and Tal Einat have joined Titus and myself in administering this list.

And while I'm thinking about it, just a reminder about how to let us know about CoC violations. Please email/cc python-ideas-owner@ when you think there has been an infraction. There is enough volume on the list you can't assume we read every email. We also try to stay objective on this topic so chances are we won't bring up any CoC issues in order to stay neutral.
