`nix store delete nixpkgs#hello` first downloads hello before deleting it

[lisanna-dettwyler]

Describe the bug

Passing a flake attribute to nix store delete will first cause it to be downloaded before being deleted. This is a bit unintuitive.

Steps To Reproduce

✗ nix store delete nixpkgs#hello
this path will be fetched (0.05 MiB download, 0.26 MiB unpacked):
  /nix/store/aiblla3swfhcv348k8h10mnsg35wzvm6-hello-2.12.2
1 store paths deleted, 0.00 MiB freed

Expected behavior

I think it should instead error saying that it does not exist.

Metadata

nix-env (Nix) 2.31.2
