[NITPICK] Keep server.ts template and server.ts in our storefrontapp as similar as fresh angular's created server.ts for consistency.

[pawelfras]

          [NITPICK] Can be done in a separate PR/ticket as "further improvements" later:

For consistency, this server.ts template and server.ts in our storefrontapp, ideally, should be (nearly) the same as fresh angular's created server.ts.

So let's use:

import { fileURLToPath } from 'node:url';
import { dirname, join, resolve } from 'node:path';

and later on:

  const serverDistFolder = dirname(fileURLToPath(import.meta.url));
  const browserDistFolder = resolve(serverDistFolder, '../browser');
  const indexHtml = join(serverDistFolder, 'index.server.html');
