📝 docs(constants.tsx): add documentation for TWEAKS constant

The TWEAKS constant is a dictionary that can be used to tweak the flow. It is an optional parameter that can be passed to the run_flow function. The dictionary should be in the format {"OpenAI-XXXXX": {"model_name": "gpt-4"}}. This commit adds documentation to the code to make it easier for developers to understand how to use the TWEAKS constant.
