az policy state list - Error: The http method 'GET' is not supported for 'queryResults' when more than 1000 records returned

## Describe the bug

**Command Name**
`az policy state list`

**Errors:**
```
(HttpMethodNotSupported) The http method 'GET' is not supported for 'queryResults'.
Code: HttpMethodNotSupported
Message: The http method 'GET' is not supported for 'queryResults'.
```

Running with `--debug` flag I see the initial API call is a POST with subsequent call a GET (some details were snipped):
