Support yarn v2

[fifn2]

Yarn v2 has a new directory structure that doesn't involve modules. eslint-plugin-import was able to solve an issue like this quite easily by using createRequireFromPath instead of require.resolve.

git-cz cli works for me in yarn-2.0.0-rc.36. below is my project setup.

Install

$ yarn add commitizen cz-lerna-changelog

package.json

{
  "config": {
    "commitizen": {
      "path": "cz-lerna-changelog"
    }
  }
}

Script

$ yarn git-cz

I think the docs should probably be updated to reflect this, but here's my current config with the newest version of husky:

package.json

{
  "config": {
    "commitizen": {
      "path": "cz-<your flavor>" // Notice the lack of ./node_modules
    }
  }
}

.husky/prepare-commit-msg

#!/bin/bash
exec < /dev/tty && yarn cz --hook || true # notice the lack of node_modules/.bin and instead using yarn

I would argue that if this is added to the docs, this issue should be closed.
