Docker tag nixos/nix:2.22.0 does not include arm64 arch

[nebez]

Describe the bug

nixos/nix:latest and nixos/nix:2.22.0 both no longer include arm64 arch. The latest tagged version that still works is nixos/nix:2.21.2.

Steps To Reproduce

docker pull nixos/nix:2.22.0

2.22.0: Pulling from nixos/nix
no matching manifest for linux/arm64/v8 in the manifest list entries

Expected behavior

docker pull nixos/nix:2.21.2

2.21.2: Pulling from nixos/nix
Digest: sha256:8954cfd0905419770e6ded1b5c4f0071a8f564a8668a21cd0f288b9cd9b8b62f
Status: Image is up to date for nixos/nix:2.21.2
docker.io/nixos/nix:2.21.2

Would expect 2.22.0 to also work across both amd64 and arm64.

It looks like the arm64 image didn't get uploaded for some reason. I've rerun the release script so it should be there now.

I (still) only see linux/amd64 on the default tag.
