incorrect usage example in README

[catdad]

The current usage example in github and npm, for the latest version v1.0.2, is:

const chai = require('chai')
const chaiJestDiff = require('chai-jest-diff')

chai.use(chaiJestDiff())

This code does not work and it throws:

  ● Test suite failed to run

    TypeError: _get__(...) is not a function

      3 | const chaiJestDiff = require('chai-jest-diff');
      4 |
    > 5 | chai.use(chaiJestDiff());
        |          ^
      6 | const { expect } = chai;

When using es module import in my code, this works:

import chai from 'chai';
import chaiJestDiff from 'chai-jest-diff';

const { expect } = chai;

chai.use(chaiJestDiff());

However, when using require like in the example in the readme, I need to do this:

const chai = require('chai');
const chaiJestDiff = require('chai-jest-diff');

chai.use(chaiJestDiff.default());
const { expect } = chai;

If nothing else, can the README please be updated so that others know how to use this module?
