Python snippets do not show @odata.* properties correctly.

Examples 2 & 3 from Create group have this:

additional_data = {
    "owners@odata_bind" : [
        "https://graph.microsoft.com/v1.0/users/99e44b05-c10b-4e95-a523-e2732bbaba1e",
    ],
    "members@odata_bind" : [
        "https://graph.microsoft.com/v1.0/users/6ea91a8d-e32e-41a1-b7bd-d2d185eed0e0",
        "https://graph.microsoft.com/v1.0/users/4562bcc8-c436-4f95-b7c0-4f8ce89dca5e",
    ],
}

The correct property names should use a ., not a _, so the correct code should be:

additional_data = {
    "[email protected]" : [
        "https://graph.microsoft.com/v1.0/users/99e44b05-c10b-4e95-a523-e2732bbaba1e",
    ],
    "[email protected]" : [
        "https://graph.microsoft.com/v1.0/users/6ea91a8d-e32e-41a1-b7bd-d2d185eed0e0",
        "https://graph.microsoft.com/v1.0/users/4562bcc8-c436-4f95-b7c0-4f8ce89dca5e",
    ],
}
