Error when trying to deploy:
@ngx-env/builder:application (angularski:build:production) is not a recognized builder. Please check your angular.json
```

### Expected behavior

Deploy

### Actual behavior

Failed to deploy

從 angular.json 設定開始，使用 issue 中列出的版本透過 ng deploy 重現回報的失敗。比較在 AngularFire/Firebase Hosting 部署期間如何解析 @ngx-env/builder:application；當回報的專案能夠部署且不再出現 unrecognized-builder 錯誤時，即表示完成。
