`@nx/enforce-module-boundaries` incorrectly allows deep imports

[Katli95]

Current Behavior

Given our repro repo

@here/cart can import from packages/utilities/src/private/private.ts via @here/utilities/src/private/private even though it's not explicitly exported from packages/utilities/src/index.ts

Expected Behavior

A lint error at import { privatePrivate } from '@here/utilities/src/private/private'; saying something like "only root level exports can be imported"
