Fails to load polyfill using native node ESM

[perrin4869]

Reproducible on latest node 16.3.0:

❯ cat package.json
{
  "type": "module",
  "devDependencies": {
    "cross-fetch": "^3.1.4"
  }
}
❯ cat index.js
import "cross-fetch/polyfill";
❯ node --experimental-specifier-resolution=node index.js
node:internal/process/esm_loader:74
    internalBinding('errors').triggerUncaughtException(
                              ^

Error [ERR_MODULE_NOT_FOUND]: Cannot find module '/home/perrin4869/univapay/cross-fetch-esm/node_modules/cross-fetch/polyfill' imported from /home/perrin4869/univapay/cross-fetch-esm/index.js
Did you mean to import cross-fetch-esm/node_modules/cross-fetch/dist/node-polyfill.js?

}

Not sure if this should be treated as a node bug or as a cross-fetch bug though...
