Confirm this is a Node library issue and not an underlying OpenAI API issue

• [X] This is an issue with the Node library

Describe the bug

The type of AutoParseableTool is incorrectly describing $callback as receiving the arguments zod schema as input while it should have the inferred zod type of the arguments zod schema.

To Reproduce

1. Define a tool with the import { zodFunction } from 'openai/helpers/zod'; helper.
2. Check the inferred type of $callback property on the tool.

Code snippets

Can be fixed by adding zodInfer<...> here: https://github.com/openai/openai-node/blob/3fdc7d4f67a6ceea51723684dcc0bc1895088259/src/lib/parser.ts#L66-L77

So $callback will become:

$callback: ((args: zodInfer<OptionsT['arguments']>) => any) | undefined;
