Unauthenticated downloads of build artifacts

Unfortunately, unauthenticated downloads don't work for artifacts from GH actions. This makes automated local DB updates unnecessarily difficult.

Would be nice to have artifacts in GH releases.

That's unfortunate. I've wanted to use releases for, well, releases but I guess we can do the same split nix-index does. Thanks for letting me know. I'll take a look at this later.
