Update for Bevy 0.18

[stewartadam]

I needed to update to Bevy 0.18 so asked Codex to update update moonshine_kind based on the 0.17->0.18 migration guide.

Changes look small and reasonable given the introduction of the new IS_ARCHETYPAL constant upstream.

Hello! Sorry, I've been busy and lagging behind on the 0.18 update.
I have all the Moonshine libraries updated locally, just haven't had a chance to test/publish. I'll try to get it done in the next couple of days or so.

Your CL is correct though. It's fairly straightforward. If you want, you can take over, or just wait for me to publish. Up to you :)

Either way, thank you for this!

No worries, I've had a crazy January too - I figured I'd share in case it helped, if you've got it all staged locally I'll close this out! I'm unblocked for now since I pointed Cargo at my fork's branch.
