Inferred function types without generics compile to any

[jld-adriano]

Bug description

When compiling inferred function types, the output is not as expected

Input

export default function test(input: string) {
  return {
    test: input,
  };
}
export type Test = typeof test;
export type AsType = (input: string) => { test: string };

Expected output

// Generated by ts-to-zod
import { z } from "zod";

export const testSchema = z
  .function()
  .args(z.string())
  .returns(
    z.object({
      test: z.string(),
    })
  );

export const asTypeSchema = z
  .function()
  .args(z.string())
  .returns(
    z.object({
      test: z.string(),
    })
  );

Actual output

// Generated by ts-to-zod
import { z } from "zod";

export const testSchema = z.any();

export const asTypeSchema = z
  .function()
  .args(z.string())
  .returns(
    z.object({
      test: z.string(),
    })
  );
