roles filetree_create export missing instance_groups key

[w4hf]

Summary

When exporting roles using filetree_create, the instance_groups key is missing from the generated yaml file resulting in an invalid yaml file

example, if the team DB Team is assigned admin role on the instance group Test IG, the generated role looks like the following :

---
controller_roles:
  - team: "DB Team"
      - "test IG"
    role: "admin"
  - team: "QA Team"
    inventories:
      - "Demo Inventory"
    role: "admin"

You can see that the keyword instance_groups is missing between line 2 and 3
The error is also present for users

Desired Behavior

The exported roles file contains the instance_groups keyword

Actual Behavior

The exported roles file does not contains the instance_groups keyword

## STEPS TO REPRODUCE

1. assign a team or a user a role on an instance group
2. export roles using filetree_create
3. see that the generated yaml file is invalid because it is missing the `instance_groups` key

```yaml (playbook/task)
ansible-playbook filetree_create.yml -e flatten_output=true -vv -e '{input_tag: [roles]}'
