NAIP example with scheme of "none" is incongruent

The NAIP Item example has a scheme:

```
 "none": {
        "type": "http",
        "scheme": "basic",
        "description": "Free access without restrictions"
      }
```

The name `none` and `Free access without restrictions` seems incongruent with the fact that the scheme `basic` is used here, indicating that Basic Authentication is required, not "none" and "free access"
