[ethers-v4] New factories folder causing module resolution problem.

[alexroan]

Since this fix, I'm getting the following issue inside a generated factory:

src/generated/factories/LinkToken__factory.ts(9,38): error TS2307: Cannot find module '.'

It appears this line is trying to import TransactionOverrides from the factories folder:

import { TransactionOverrides } from ".";

This works if the "." becomes ".."

Looks like you're right -- we must've missed it since most of us use ethers v5 by now :)
Seems like an easy fix, could you prepare a PR?
