doc: improve createRequire example

[MylesBorins]

Original doesn't really make sense in retrospect

updates example to

// cjs.js module.exports = 'cjs'; // esm.mjs import { createRequireFromPath as createRequire } from 'module'; import { fileURLToPath as fromURL } from 'url'; const require = createRequire(fromURL(import.meta.url)); const cjs = require('./cjs'); cjs === 'cjs'; // true

Can you please target the docs branch?

Out of scope for this PR, but I just read the createRequireFromPath docs and they don’t explain why you’d want a require function where the argument it’s given is relative to some folder other than the one the current file is in. It seems pretty pointless outside of the ESM import.meta.url context.
