Both id and urn used in schema

[pawelprazak]

The provider uses id and urn and probably should not have:

        "ovh:Cloud/getProjectIam:getProjectIam": {
            "properties": {
                ...
                "id": {
                    "type": "string",
                    "description": "Unique identifier of the resource in the IAM\n"
                },
                ...
                "urn": {
                    "type": "string",
                    "description": "URN of the private database, used when writing IAM policies\n"
                }
            }
