Describe the feature or improvement you're requesting

I updated the code to use GPT-3.5-turbo. Feel free to copy my code from my fork @ https://github.com/CaseySMiller/openai-quickstart-node

I also wasn't able to get .env variables from ./.env so changed it to ./.env.local

I updated the readme to reflect this.

Additional context

• Updated the .env.example file name
• Updated readme to reflect .env change
• Changed to newest version of openai library in package.json
• Modified ./pages/api/generate.js to call createChatCompletion instead of the createCompletion method and pass it a correctly formatted object
• Happy copy/pasting ;)
