The example i18n project referenced in the latest documentation is using old (<9) style localization configuration, and the source code does not match the documented instructions

🔬 Minimal Reproduction

What's the affected URL?**

https://angular.io/guide/i18n#translate-attributes

Expected vs Actual Behavior**

Would have expected a section in the angular.json similar to:

"i18n": {
      "sourceLocale": "en-US",
      "locales": {
        "fr": "src/locale/messages.fr.xlf"
      }
    }
