Fix OpenAI returns "Unrecognized request argument supplied: api_key"

Hello guys!

I was testing this lib, when I came across the error Unrecognized request argument supplied: api_key that ChatGPT than returned when execute the LLMChain.run

So I looked deeper into what the problem was and discovered that this line bellow:

def for_api(%ChatOpenAI{} = openai, messages, functions) do
  %{
    model: openai.model,
    api_key: openai.api_key, # this line is not necessary, because this go into body request
    temperature: openai.temperature,
    frequency_penalty: openai.frequency_penalty,
    n: openai.n,
    stream: openai.stream,
    messages: Enum.map(messages, &ForOpenAIApi.for_api/1),
    response_format: set_response_format(openai)
  }
  |> Utils.conditionally_add_to_map(:seed, openai.seed)
  |> Utils.conditionally_add_to_map(:functions, get_functions_for_api(functions))
end

When I removed the line api_key: openai.api_key the response is success from ChatGTP.

Error with api_key sended on body:

{
    "error": {
    "message": "Unrecognized request argument supplied: api_key",
    "type": "invalid_request_error",
    "param": null,
    "code": null
  }
}

After fix this, API returns sucess!

Sorry if I'm wrong
