## Invoke the `Router.lastSuccessfulNavigation` signal migration

`Router.lastSuccessfulNavigation` is now a signal, this migration ensures `Router.getCurrentNavigation` is invoked:

### Before

```typescript
import {Router} from '@angular/router';

export class MyService {
  router = inject(Router);

  someMethod() {
    const navigation = this.router.lastSuccessfulNavigation;
  }
}
```

### After

```typescript
import {Router} from '@angular/router';

export class MyService {
  router = inject(Router);

  someMethod() {
    const navigation = this.router.lastSuccessfulNavigation();
  }
}
```
