Incorrect example for read authorization models

[adriantam]

The example listed in read authorization models is incorrect. Currently, it reads

{
  "authorization_models": [
    {
      "id": "01G50QVV17PECNVAHX1GG4Y5NC",
      "type_definitions": [...]
    },
    {
      "id": "01G4ZW8F4A07AKQ8RHSVG9RW04",
      "type_definitions": [...]
    },
  ]
  "continuation_token": "eyJwayI6IkxBVEVTVF9OU0NPTkZJR19hdXRoMHN0b3JlIiwic2siOiIxem1qbXF3MWZLZExTcUoyN01MdTdqTjh0cWgifQ=="
}

Notice there is a missing comma before continuation token. Instead, it should be

{
  "authorization_models": [
    {
      "id": "01G50QVV17PECNVAHX1GG4Y5NC",
      "type_definitions": [...]
    },
    {
      "id": "01G4ZW8F4A07AKQ8RHSVG9RW04",
      "type_definitions": [...]
    },
  ],
  "continuation_token": "eyJwayI6IkxBVEVTVF9OU0NPTkZJR19hdXRoMHN0b3JlIiwic2siOiIxem1qbXF3MWZLZExTcUoyN01MdTdqTjh0cWgifQ=="
}
