README: Explain OpenAI billing for API key (Fixes issue about "API Rate Limit Reached. Waiting 20 seconds ... Failed to get response after 5 retries")

[JuroOravec]

Background

There's multiple issues, where people hit OpenAI API rate limiting error, where the true cause of the rate limiting is that people have not set up billing (paid account) on their OpenAI profile.

The truth is, one has to:

1. Opt in to "paid account" on https://platform.openai.com/account/billing/overview and enter their billing info
2. Only now request the API key (in my case it took about 5-10 mins after opting into paid account before the API key started to work via AutoGPT.

As of 12:00 14/04/2023, I found these related issues:

I have set up a paid openai and still get the error Warning: The file 'auto-gpt.json' does not exist. Local memory would not be saved to a file.
Please set your OpenAI API key in .env or as an environment variable.
You can get your key from https://beta.openai.com/account/api-keys

这就是 README 部分在更改后的样子

OpenAI can set up paid accounts, is there a limit for the region, which regions can set up?
