datree: Missing openshift api-resources

Hey,

I am playing around with datree but fail to get a working validation with specific OpenShift api resources. I exported the resources via the crd extractor tool but datree just throws an error:

helm template ~/work/mychart/ -f ~/work/mychart/values/myproject/values.yaml | datree test - --schema-location '$HOME/.datree/crdSchemas/{{.ResourceKind}}_{{.ResourceAPIVersion}}.json'
>>  File: /tmp/datree_temp_362123854.yaml

[V] YAML validation
[X] Kubernetes schema validation

❌  k8s schema validation error: could not find schema for Group

❌  k8s schema validation error: could not find schema for Group

To troubleshoot: refer to our docs [https://hub.datree.io/troubleshooting#schema-validation-failure]
To ignore this failure: use the CLI flag `--ignore-missing-schemas`

[?] Policy check didn't run for this file


(Summary)

- Passing YAML validation: 1/1

- Passing Kubernetes (1.20.0) schema validation: 0/1

- Passing policy check: 0/1

I double checked what the crd extractor extracted and the group json schema is part of it:

{
  "description": "Group represents a referenceable set of Users",
  "type": "object",
  "required": [
    "users"
  ],
  "properties": {
    "apiVersion": {
      "description": "APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources",
      "type": "string"
    },
    "kind": {
      "description": "Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds",
      "type": "string"
    },
    "metadata": {
      "$ref": "_definitions.json#/definitions/io.k8s.apimachinery.pkg.apis.meta.v1.ObjectMeta"
    },
    "users": {
      "description": "Users is the list of users in this group.",
      "type": "array",
      "items": {
        "type": "string"
      }
    }
  },
  "x-kubernetes-group-version-kind": [
    {
      "group": "user.openshift.io",
      "kind": "Group",
      "version": "v1"
    }
  ],
  "$schema": "http://json-schema.org/schema#"
}

Is there something wrong with the schema?

Thanks
