[Docs] [compat-oai] Incorrect example initialization code for OpenAI

[Tyg-g]

Is your report related to a problem? Please describe.

I believe the readme contains incorrect or incomplete initialization code:

import dotenv from 'dotenv';
import { genkit } from 'genkit';
import openAI, { gpt35Turbo } from '@genkit-ai/compat-oai';

dotenv.config();

const ai = genkit({
  plugins: [openAI({ apiKey: process.env.OPENAI_API_KEY })],
  // specify a default model if not provided in generate params:
  model: gpt35Turbo,
});

As it throws the error:

TypeError: Cannot read properties of undefined (reading 'name')
    at openAICompatible (file:///{project}/node_modules/@genkit-ai/compat-oai/lib/index.mjs:7:13)

Is your report related to a suggestion/improvement? Please describe.

To use the OpenAI models, the import line should look like this:

import openAI from '@genkit-ai/compat-oai/openai';

Additional context
None.
