[Bug] ExpressionChangedAfterItHasBeenCheckedError happens when provideExperimentalZonelessChangeDetection() is enabled

[mtycholaz]

Steps to reproduce

1. Create an Angular 19 project.
2. In the app.config provide toastr and provideExperimentalZonelessChangeDetection
3. Create a new toastr notification

Very easy to reproduce. Appears to happen because of the setTimeout in the onActivated function of the ToastRef. Angular wraps setTimeout to make it work with zone.js but with that gone, the setTimeout will now need to be updated so that it runs within the context of Angular.
