JavaScript アクションでも ES Module を使いたい [GitHub Actions]

file:///home/runner/work/nostr/nostr/webpack:/javascript-action/external node-commonjs "os":1
module.exports = require("os");
^
ReferenceError: require is not defined in ES module scope, you can use import instead
This file is being treated as an ES module because it has a '.js' file extension and '/home/runner/work/nostr/nostr/dist/package.json' contains "type": "module". To treat it as a CommonJS script, rename it to use the '.cjs' file extension.
