Make Zulip IDs required

[Kobzol]

This PR makes Zulip ID required for all active team members, with the exception of an allowlist consisting of a few current team members for which we didn't find their Zulip ID yet.

If you use the Rust Zulip, please post your Zulip account ID here, thank you! (you can find it by clicking on your profile image in the top right corner, then selecting "View your profile", and the ID will appear in the URL).

The proposal to require zulip IDs explicitly mentions that the requirement should only extend to project team members and not marker teams. Given that I am only on the windows marker team, and not part of a standard team, this requirement should not apply to me and thus the allow list should not even be checking whether I have a zulip id to begin with.

That said, my zulip ID is 125267.

It's true that for now the T-all Zulip stream is meant for team members. That being said, I think that we'd eventually want to get rid of the marker team concept (EDIT: I meant to get rid of current marker teams that should just be normal teams. Having marker teams that are not officially a part of the Project makes sense, but we first need to clean up our current marker teams), and my assumption was that we would require Zulip ID for anyone added to the team database from now on.

It would be good to clarify this though, I'll add it to the council issue.
