🚀 Describe the new functionality needed

Overall, the expected functionality should look like this:

from openai import OpenAI
client = OpenAI()

response = client.responses.create(
  prompt={
    "id": "pmpt_68b0c29740048196bd3a6e6ac3c4d0e20ed9a13f0d15bf5e",
    "version": "2",
    "variables": {
        "city": "San Francisco",
        "age": 30,
    }
  }
)

Where the prompt_id and variables are generated from the Prompts API.

💡 Why is this needed? What if we don't build it?

Otherwise we are not compatible with Responses API.
