Tutorial crawling a website

The tutorial web-qa-embeddings mentions how to set up an OpenAI API key. However it would
be helpful if after import openai in the notebook web-qa.ipynb
the line openai.api_key = os.getenv("OPENAI_API_KEY")
could be added. I think this would help people running the first time through the code.
Thank you!

Closed as OPEN_API_KEY will not be added to the notebook.
