Vue loader breaks with version 3.0.1

[milewski]

version v3.0.1 is missing the lib folder, which causes:

node_modules/vue-loader/lib/index.d.ts:2:37 - error TS2307: Cannot find module '@vue/component-compiler-utils/lib/types'.

2 import { VueTemplateCompiler } from '@vue/component-compiler-utils/lib/types'

It's vue-loader that has referred to the wrong entry, actually.
But I've released a new version to fix it anyway, in case any other downstream libraries made the same mistake.
