Broken _get_kwargs code generated with JSON body type string

[Gelbpunkt]

Describe the bug
With a route definition that sets the content type to application/json but the schema type to a string, the code generated references an invalid variable.

To Reproduce

1. Add a route definition like so:

        "/chat/web": {
            "parameters": [],
            "post": {
                "security": [
                    {
                        "basicAuth": []
                    }
                ],
                "description": "Send a message to the chat",
                "responses": {
                    "204": {
                        "description": "Message sent"
                    } 
                },
                "requestBody": {
                    "description": "The text to send",
                    "required": true,
                    "content": {
                        "application/json": {
                            "schema": {
                                "type": "string"
                            }
                        }
                    }
                }
            }
        }

2. Run openapi-python-client update ...
3. Open the python file at api/.../post_chat_web.py
4. See _get_kwargs code

def _get_kwargs(
    *,
    client: AuthenticatedClient,
    json_body: str,
) -> Dict[str, Any]:
    url = "{}/chat/web".format(client.base_url)

    headers: Dict[str, Any] = client.get_headers()
    cookies: Dict[str, Any] = client.get_cookies()

    return {
        "url": url,
        "headers": headers,
        "cookies": cookies,
        "timeout": client.get_timeout(),
        "json": json_json_body,
    }

Expected behavior
The code in post_chat_web.py should reference json_body and not json_json_body.

Thanks for reporting this! Sorry for the delayed response, I'll add this into my list of bugs to reproduce & fix this weekend.

Sorry for the delays, I finally got around to fixing this in #550. Will be included in 0.10.8 release. Not the prettiest code ever but at least it functions now!
