The return type hint of `client.audio.transcriptions.create()` is incorrect.

[gbaian10]

Confirm this is an issue with the Python library and not an underlying OpenAI API

• [X] This is an issue with the Python library

Describe the bug

The return type hint of client.audio.transcriptions.create() is Transcription, and this type has a text attribute.

However, when the response_format is equal to text, srt, or vtt, its return value is str. In this case, calling the text attribute will result in an error.

To Reproduce

import openai
from dotenv import load_dotenv

load_dotenv()

file_path = "example.wav"

client = openai.OpenAI()
with open(file_path, "rb") as file:
    transcript = client.audio.transcriptions.create(
        model="whisper-1", file=file, response_format="srt"
    )

    print(transcript)
    print(type(transcript))
    print(transcript.text)
    print(type(transcript.text))
