Describe the bug

Lix fails to build using the hashes published on https://lix.systems/add-to-config/.

Steps To Reproduce

Add the following to Nix config imports:

      (let
        module = fetchTarball {
          name = "source";
          url = "https://git.lix.systems/lix-project/nixos-module/archive/2.93.3-1.tar.gz";
          sha256 = "sha256-KYMUrTV7H/RR5/HRnjV5R3rRIuBXMemyJzTLi50NFTs=";
        };
        lixSrc = fetchTarball {
          name = "source";
          url = "https://git.lix.systems/lix-project/lix/archive/2.93.3.tar.gz";
          sha256 = "sha256-Oqw04eboDM8rrUgAXiT7w5F2uGrQdt8sGX+Mk6mVXZQ=";
        };
        # This is the core of the code you need; it is an exercise to the
        # reader to write the sources in a nicer way, or by using npins or
        # similar pinning tools.
        in import "${module}/module.nix" { lix = lixSrc; }
      )

Then run a regular nixos-build switch --upgrade.

Expected behavior

Lix successfully builds.

Actual behavior

`nix --version` output

nix (Lix, like Nix) 2.91.1

Additional context

I can't rebuild 2.91.1, 2.92.0-3, or 2.93.0 because of the following error:

error: separateDebugInfo = true in lix requires __structuredAttrs if {dis,}allowedRequisites or {dis,}allowedReferences is set

this is a duplicate of .. something, the root cause of this bug is nixpkgs breakages causing burnout that causes not releasing a 2.93.4 with fixes that are already in a branch. please use nixosModules.lixFromNixpkgs or switch both module and lix to release-2.93 or use the running main guide at wiki.lix.systems.
