[Pkg-javascript-devel] Export both ESM and CommonJS modules

[Yadd]

Hi all,

some recent updates switched from CommonJS to ESM ("type: module"). I
found a way for node-strip-json-comments which can be applied to most of
Sindre Sorhus modules:

 1. build a commonjs file:

	babeljs -o index.cjs index.js
	perl -i -pe 's/^export default/module.exports =/' index.cjs

 2. adapt package.json:

	--- a/package.json
	+++ b/package.json
