Fix Odoo Community resource

The Odoo API adds a community field as first level in the community response:

• Before:

{
  "id": 123,
  "name": "Model Osona",
  "birth_date": "2021-11-14",
  ...
}

• After:

{
  "community": {
    "id": 123,
    "name": "Model Osona",
    "birth_date": "2021-11-14",
    ...
  }
}

We must adapt the resource in our project to manage this new level in JSON response.
