DeprecationWarning: The 'punycode' module is deprecated when running ng add @angular/fire

## DeprecationWarning: The 'punycode' module is deprecated when running ng add @angular/fire

**Description:**

When adding `@angular/fire` to a new Angular 19 application using the `ng add @angular/fire` schematic, a `DeprecationWarning` related to Node.js's `punycode` module is displayed.


**Versions:**

* **Angular CLI:** (Please specify, e.g., `19.x.x`)
* **Angular Core:** (Please specify, e.g., `19.x.x`)
* **@angular/fire:** (Please specify the version installed by `ng add`, check `package.json`)
* **Node.js:** (Please specify, e.g., `v18.x.x`, `v20.x.x`)
* **firebase-tools:** `14.2.2` (as per the log)

**Steps to Reproduce:**

1. Create a new Angular 19 application:
```bash
ng new my-angular-app
cd my-angular-app
```
2. Run the `ng add @angular/fire` schematic:
```bash
ng add @angular/fire
```
3. During the installation and setup process, select the following Firebase features when prompted:
* Authentication
* Firestore
* Realtime Database

**Expected Behavior:**

The `ng add @angular/fire` schematic should complete without displaying deprecation warnings related to Node.js modules.

**Current Behavior:**

During the execution of the schematic, after selecting Firebase features and while dependencies are being installed or files are being configured, the following warning appears in the console:


`ng add @angular/fire`を実行してAuthentication、Firestore、Realtime Databaseを選択し、新しいAngular 19アプリケーションで警告を再現します。`punycode`警告の発生源を特定するため、schematicの依存関係のインストールと設定出力を調査します。この非推奨警告が表示されずにセットアップが完了すれば完了です。
