Direct template loading in AngularWebpackPlugin results in empty component templates

### Command

build

### Is this a regression?

- [x] Yes, this behavior used to work in the previous version

### The previous version in which this bug was not present was

18.3.0

### Description

A bugfix in webpack 5.96.0 has broken direct template loading.
https://github.com/webpack/webpack/issues/19235#issuecomment-2688250063

When using webpack 5.96.0 or higher, if you set the `directTemplateLoading` option to false in the `AngularWebpackPlugin`, component templates end up being empty.

Note: I've said that this is a regression even though technically nothing in the Angular CLI has changed, however if you are updating the Angular CLI regularly, you are probably also updating webpack regularly, so you will encounter this bug.

### Minimal Reproduction

Start with this repository: https://github.com/reduckted/repro-webpack-template

This is the setup:
- Contains `AppComponent` that has a template with the content "hello world".
- A custom Angular builder is used to modify the webpack configuration and set `AngularWebpackPlugin.options.directTemplateLoading` to false.
- A custom loader is to the webpack configuration that replaces all occurrences of "world" with "you" in HTML files.

When this works, the `AppComponent`'s template will end up containing "hello you".

Start by cloning the repository:
```
git clone https://github.com/reduckted/repro-webpack-template.git
cd repro-webpack-template
```

Switch to the `ng-webpack595` branch (this uses webpack@5.95.0). and build:

```
git checkout ng-webpack595
npm i
npm run build
```
Open `dist/repro-webpack-template/main.js` and search for "AppComponent_Template". You will see that it looks like this:

```js
template: function AppComponent_Template(rf, ctx) {
if (rf & 1) {
_angular_core__WEBPACK_IMPORTED_MODULE_0__["ɵɵtext"](0, "hello you\n");
}
},
```

This works correctly and has replaced "world" with "you".

Now switch to the `ng-webpack598` branch (this uses webpack@5.98.0). and build:

```
git checkout ng-webpack598
npm i
npm run build
```

Open `dist/repro-webpack-template/main.js` again and search for "AppComponent_Template". You will see that it looks like this:
```js
template: function AppComponent_Template(rf, ctx) {},
```

The template is completely empty.

### Anything else relevant?

As @alexander-akait says here: https://github.com/webpack/webpack/issues/19235#issuecomment-2688250063

> it was a bug fix in 5.96.0 and unfortunately your code relied on buggy behavior.

Thankfully, the fix is really simple, and @alexander-akait even provided an example of how to fix it. :heart:

This:
https://github.com/angular/angular-cli/blob/cb078c276861ce6fb6aaebc589b3c44fcb854c38/packages/ngtools/webpack/src/resource_loader.ts#L129

Needs to change to:
```ts
return `data:application/javascript,export { default } from "${filePath}?${NG_COMPONENT_RESOURCE_QUERY}";`;
```

Commencez dans packages/ngtools/webpack/src/resource_loader.ts, au niveau de la logique de chargement des ressources référencée dans le rapport, puis reproduisez le comportement à l’aide des branches ng-webpack595 et ng-webpack598. Vérifiez la sortie du build avec directTemplateLoading=false en inspectant AppComponent_Template dans dist/repro-webpack-template/main.js. C’est terminé lorsque le template traité n’est plus vide et contient toujours le contenu transformé "hello you".
