Fix CRA + Less modules test crash

[maxwowo]

Right now if you use the following config

const path = require('path');

const CracoAntDesignPlugin = require("craco-antd");
const CracoLessPlugin = require('craco-less');

module.exports = {
  plugins: [
    {
      plugin: CracoLessPlugin,
      options: {
        lessLoaderOptions: {
          javascriptEnabled: true
        }
      }
    },
    {
      plugin: CracoAntDesignPlugin,
      options: {
        cssLoaderOptions: {
          modules: {
            localIdentName: '[local]_[hash:base64:5]'
          }
        },
        modifyLessRule: function (lessRule, _context) {
          lessRule.test = /\.(module)\.(less)$/;
          lessRule.exclude = /node_modules/;

          return lessRule;
        }
      }
    }
  ]
};

and hit yarn test, the test will fail and crash with the following error message I did some research and found out that if we replaced "es" with "lib" when configuring the Antd babel plugins, it'd fix the problem. I don't know why that works though :(

Hello, thanks for the PR! I think this might be fixing the issue by referring to the compiled files in lib, instead of the source files. But I'm not sure if this is the correct solution either, or if it will break someone else's project.

Maybe this should be configurable as an option. If you have some time, would it be possible to add this is a configurable setting (with es as the default), and update the README with some instructions?

Thanks again for the PR! Sorry I can't jump in and contribute more, but I'm always happy to merge a PR with good test coverage and documentation.

Hello, if you are still interested in contributing, could you please rebase your changes onto the master branch and see if all of the tests are still passing?

[maxwowo]

Yep sure thing, just been a bit busy recently, will do that soon

Hey @ndbroadbent , this seems ready, can you merge it please?

[ndbroadbent]

Hello, I've merged the changes and pushed a new version: 1.18.1. Thanks!

This pull request broke my tests/ project.

I'm using es and not lib. Is there an option to configure this now?!

@ndbroadbent this is causing end bundle to include all icons from @ant-design/icons, instead of only used ones.
