Angular animations package is deprecated, ngx-bootstrap not working without

[PapaNappa]

Since Angular 20.2, the @angular/animations package is deprecated. Angular has a new set of features for animations, mostly based on native CSS transitions and keyframes.

Removing the BrowserAnimationsModule or provideAnimations() from the providers results in errors for ngx-bootstrap components, such as dropdown and collapse.

As per the current documentation, Angular intents to remove the old animations package with Angular v23.

Migrating away from the animations package would allow developers to save on bundle size even today. As of today, this issue prevents developers to migrate away.
