Bug: Zod function types not inferred correctly

[GiveMe-A-Name]

Detail

Zod types generate function always carry a unknown[] args.
But it's a difference from (...args: unknown[]) => string; between () => string;

Code

import { z } from "zod";

const myFunction = z.function().returns(z.string());

// MyFunction1 type is (...args: unknown[]) => string;
type MyFunction1 = z.infer<typeof myFunction>;

const f1: MyFunction1 = (x1: string) => "";

// Expect type is () => string;
type MyFunction2 = () => string;

const f2: MyFunction2 = () => "";
