fix: correct typo in API section title and update links, and adjust provider aliases

- Changed "Inference API" to "Interference API" and updated corresponding documentation links in README.md
- Removed "o1" and "dall-e-3" entries from Copilot.py model_aliases
- Added "stream" and "extra_body" parameters with default values in Azure.py's create_async_generator method
- In CopilotAccount.py, included model_aliases with "gpt-4", "gpt-4o", "o1", and "dall-e-3"
- Updated conditional for provider comparison from "==" to "in" list in any_provider.py
- Modified g4f/api/__init__.py to set g4f_api_key from environment variable
- In backend_api.py, added "user" field to cached data with default "unknown"
- Changed logic in OpenaiTemplate.py read_response to check if "choice" exists before processing, and cleaned up indentation and conditionals in response parsing
- Removed unnecessary "stop" and "prompt" parameters from comments or unused code in OpenaiTemplate.py
- Tightened the check for "provider" comparison in any_provider.py to handle multiple providers properly
