Subject: [PATCH 13/16] gnu: js-commander: Install as a node module.

From: Philip McGrath <[email-masked]>
Date: Thu, 9 Nov 2023 11:26:35 -0500

Previously, NPM would not find 'commander' when resolving dependencies.

In case anyone is using it, keep building the bundled version at
'share/javascript/commander/index.min.js', too.

* gnu/packages/javascript.scm (js-commander)[build-system]: Use
'node-build-system'.
[arguments]: Delete unpackaged 'devDependencies'.  Build bundle for
compatibility.
