✨ Add disk encryption key to GCP compute disks (#795)

```typescript
./cnquery run gcp -c "gcp.project.compute.disks{name diskEncryptionKey}"

gcp.project.compute.disks: [
  0: {
    diskEncryptionKey: {}
    name: "gke-mondoo-gke-cluster-2-generic-pool-738078cc-1bdm"
  }
  1: {
    diskEncryptionKey: {}
    name: "gke-mondoo-gke-cluster-2-generic-pool-738078cc-fhgp"
  }
  2: {
    diskEncryptionKey: {}
    name: "test-other-zone"
  }
