Tailwind JIT not updating styles when using styleUrls

### Command

serve

### Is this a regression?

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

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

_No response_

### Description

When using `styleUrls` to specify the path to the tailwind css entrypoint file separately, the JIT will not detect changes properly.

To clarify:

```ts
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.scss', '../tailwind.css'] // notice tailwind is separated here
})
```

Now if I try to use any class that is not already used in the HTML, the changes will not propagate properly. Only killing `ng serve` and restarting it will work.

I have attached a simple repro.

### Minimal Reproduction

Repro at:

https://github.com/andreialecu/angular-tw-jit-repro

Run
```
yarn
yarn start
```

Open `http://localhost:4200/` in the browser.

Then go into `app.component.html` and try to change `bg-green-200` to `bg-red-200`, you will see that the background disappears because `bg-red-200` does not exist.

If you ctrl+c then run `yarn start` again, the background will update.

Comienza con la reproducción mínima enlazada: ejecuta yarn y después yarn start, y edita app.component.html mientras tailwind.css aparece por separado en styleUrls. Observa el estilo de fondo generado antes y después de reiniciar el proceso de serve. Está terminado cuando cambiar una clase de Tailwind que antes no se utilizaba actualiza los estilos servidos sin reiniciar.
