Update planck-js to use new repository and npm for auto-update

Update planck-js configuration for cdnjs:

1. Updated repository URL from shakiba/planck.js to piqnt/planck.js
   - The original repository has been transferred, as evidenced by GitHub's redirect

2. Changed auto-update source from git to npm
   - The npm package "planck" is now the primary distribution method

3. Updated auto-update target to "planck" to match the current npm package name

These changes will allow cdnjs to fetch the latest versions of planck-js from the correct source, ensuring users have access to the most up-to-date files.
