dockerTools.pullImage: errors from skopeo about --src-tls-verify (difficult to repro) #133515
Description
Describe the bug
On latest unstable, The new version of the skopeo package (1.4.0, introduced in 335f187) seems to have changed something and now complains about --src-tls-verify as used here.
Steps To Reproduce
Build this docker package definition:
{ pkgs ? import <nixpkgs> { } }:
pkgs.dockerTools.pullImage
{
imageName = "alpine";
imageDigest = pkgs.lib.fakeSha256;
sha256 = pkgs.lib.fakeSha256;
finalImageName = "alpine";
finalImageTag = "latest";
}on latest nixos-unstable (and nixpkgs-unstable) with skopeo 1.4.0, and you get the following error:

Weirdly enough other definitions with actual SHA256 values (e.g. some definitions emitted from nix-prefetch-docker) do work, whereas others fail with the same message as above.
Expected behavior
Should not emit that skopeo error
