Readme CJS example fails with versions of Node older than 12.17

Using the CJS example code from the README.md seems to fail for me on all Node versions I tried before 12.17 (12.16.1, 12.15.0, 12.14.1 and 11.15.0):

#!/usr/bin/env node
const yargs = require('yargs/yargs')
const { hideBin } = require('yargs/helpers')
const argv = yargs(hideBin(process.argv)).argv

if (argv.ships > 3 && argv.distance < 53.5) {
  console.log('Plunder more riffiwobbles!')
} else {
  console.log('Retreat from the xupptumblers!')
}

The error varies by version.

12.16.1:

Error: Cannot find module 'yargs/helpers'

12.14.1 and 12.15.0:

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: <snip>/yargs-node-error/node_modules/yargs/helpers.mjs

11.15.0:

Error: Cannot find module 'yargs/helpers'

Works fine in 12.17 and 12.18.

Here’s a sample of how I set it up: https://github.com/gpoole/yargs-node-error

I researched a bit and found that yargs/yargs also exports hideBin here, therefore following change fixes the problem.

#!/usr/bin/env node
const yargs = require('yargs/yargs')
const { hideBin } = yargs
const argv = yargs(hideBin(process.argv)).argv

if (argv.ships > 3 && argv.distance < 53.5) {
  console.log('Plunder more riffiwobbles!')
} else {
  console.log('Retreat from the xupptumblers!')
}

@gpoole thank you for the bug report, this should be patched in the latest release now. @ljharb thanks for the idea of nesting inside helpers/ with an additional package.json; It feels like the latest release of yargs solves this issue, and cleans up the directory structure a bit.
