terraform GKE policies: they pass when a config block is missing

[czunker]

Describe the bug
E.g., the policy terraform-gcp-security-gke-enable-auto-repair is not applied to this GKE config:

resource "google_container_node_pool" "node_pool" {
  name       = "mondoo-operator-pool-${random_string.suffix.result}"
  location   = "us-central1-a"
  cluster    = google_container_cluster.cluster.id
  node_count = 1

  node_config {
    spot         = true
    machine_type = "e2-standard-2"
  }
}

The config block management is missing. So, the setting is missing and the policy should fail.

This applies to some more policies.

To Reproduce
Steps to reproduce the behavior:

1. Enable terraform GCP policy
2. Run cnspec against a terraform file containing above node pool.
3. See the above control is skipped.

Expected behavior
The control should fail.

Desktop (please complete the following information):

• OS: Ubuntu 22.04
• cnspec version: 7.7.1
