Update .env-template

[tardigrde]

Rename env var name to OPENAI_API_KEY.
This was needed for me to run the docker-compose (prod) setup.

Few questions:

• what about API_KEY? is it used anywhere else than inside the docker containers?
• what about EMBEDDINGS_KEY? is it needed? also see that it is used in containes (only?)

Well I realized, that in the https://github.com/arc53/DocsGPT#quickstart it says:
Create .env file in your root directory and set your OPENAI_API_KEY with your openai api key

For me this was confusing as I expected that i'd just have to rename .env-template to .env, set my key and I'm good to go. I did not realize that in the quickstart a new .env has to be setup, for which we do not have a template. Is that right?

I set the PR as draft, I guess there is no need to merge it now. What would be nice, is a more consoldiated way of treating env vars. I can help you with that, if you have an idea how you would like to have it.

EDIT: I cannot set the state to Draft
