Refs: #5851

The node-windows-tests (from unit-test.yml) failed for me on PR #5832

 Exception during run: file:///D:/a/opentelemetry-js/opentelemetry-js/api/test/tree-shaking/tree-shaking.test.ts:20
import { IFS, Union } from 'unionfs';
         ^^^
SyntaxError: Named export 'IFS' not found. The requested module 'unionfs' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from 'unionfs';
const { IFS, Union } = pkg;

This is the same type-stripping issue as #5851
