snowpackjs/rollup-plugin-polyfill-node no longer exists.

Take a look at the Warning: "Treating [module] as external dependency" part. Look at the last words. A plugin. rollup-plugin-polyfill-node, to be exact. The problem is, the link is no longer available. Of course, there is rollup-plugin-polyfill-node on GitHub.

I have no idea how to fix this, regarding my zero Svelte knowledge. Fix it, someone!
