CommonJS breakage: many consumers still use dedent = require("dedent")

[JoshuaKGoldberg]

In the (old) current version 0.7.0, dedent is published with a dist/dedent.js that sets module.exports to the dedent function:

if (typeof module !== "undefined") {
  module.exports = dedent;
}

That's meant to be used with older-style Node.js code like:

const dedent = require("dedent");

However, in e13e334, the style was switched over to ES modules style default export:

exports.default = dedent;

This is a breaking change that just hasn't been published yet. Per this Sourcegraph query for const dedent = require("dedent"), many users are still using the old style API.

Since I'm trying to keep this package stable (#36), I'm going to use https://www.npmjs.com/package/babel-plugin-add-module-exports to dial back the breaking change. That way folks can import both with the old const dedent = require("dedent") and the new import dedent from "dedent" ways.
