refactor: use export = syntax for Node utility packages

[Josh-Cena]

Pre-flight checklist

• I have read the Contributing Guidelines on pull requests.
• If this is a code change: I have written unit tests and/or added dogfooding pages to fully verify the new behavior.
• If this is a new API or substantial change: the PR has an accompanying issue (closes #0000) and the maintainers have approved on my working plan.

Motivation

We previously had some hack around module.exports to support importing these packages in both ESM and CJS, because export default will be compiled to module.exports.default = , which will work in neither ESM nor CJS (only in TypeScript, where it knows how to handle default). We didn't use export = because Babel doesn't like it unless we use another plugin. This turns out to be no longer necessary now, because we use SWC instead of Babel, which supports export = OOTB, without bringing some extra plugins.

Test Plan

Everything still works
