PEP 13: Add STAR voting and misc tidbits

[gvanrossum]

• Because this is a process PEP, and specifically the one that defines the powers of the SC, the SC does not need to approve this PEP.
• PR title prefixed with PEP number (e.g. PEP 123: Summary of changes)

Question for the SC (primarily): If I were to commit this today, it would appear to affect the upcoming election for SC2025. That's not a good idea, because we'd have to scramble to figure out exactly how to run the election. So my plan has always been to make this go into effect for the election after the upcoming one, voting for SC2026.

I can think of a few ways to implement that plan:

• Update the text of the PR slightly to explicitly state "for elections in or after 2025" or some such. (Awkward: not the text that was voted for.)
• Update the PEP now with the unstated assumption that it goes into effect next year. Not great.
• Similar, but add a .. note:: explaining that it starts after June 2025, for example. (A little awkward, but we can always remove the note once it's no longer relevant.)
• Hold off merging this PR until the upcoming election is over. (Elegant, but that means about two months until we see the change.)

What would the current SC prefer that I do?

I made a mistake here -- since PEP 13 defines the SC's powers, it's inappropriate for the SC to be involved here. I've decided to just postpone committing this PR until the upcoming election is done. See the discussion in Discourse.
