Cue policy in test file for two attestations does not work.

Description
The following is a CIP policy json that's being evaluated:

{
  "authorityMatches": {
    "keyatt": {
      "signatures": null,
      "attestations": {
        "custom-match-predicate": [
          {
            "subject": "",
            "issuer": ""
          }
        ]
      }
    },
    "keylesssignature": {
      "signatures": [
        {
          "subject": "https://kubernetes.io/namespaces/default/serviceaccounts/default",
          "issuer": "https://kubernetes.default.svc/"
        }
      ],
      "attestations": null
    },
    "keysignature": {
      "signatures": [
        {
          "subject": "",
          "issuer": ""
        }
      ],
      "attestations": null
    }
  }
}

It is incorrectly passing with this policy file here:
https://github.com/sigstore/policy-controller/blob/main/test/testdata/policy-controller/e2e/cip-requires-two-signatures-and-two-attestations.yaml
And in particular here:
https://github.com/sigstore/policy-controller/blob/main/test/testdata/policy-controller/e2e/cip-requires-two-signatures-and-two-attestations.yaml#L95

I believe this has been fixed!

Awesome, is this test passing if you uncomment this?
