📚[DOCS]: Setup on application root level

[Redaloukil]

Description

I started playing a little bit with the library as a user for a project that I am working on.

With the introduction of standalone component since Angular 14.x.x, setting up Ngxs using ngxsModule.forRoot() on a standalone root AppComponent imports is no longer possible. here is a link describing a work around

What's the affected URL?**

https://www.ngxs.io/getting-started/installation

Expected vs Actual Behavior**

Additional hint about using appConfig providers on a standalone component

export const appConfig: ApplicationConfig = {
  providers: [
    provideRouter(routes),
    importProvidersFrom(NgxsModule.forRoot([AppState])),
  ],
};

🔥 Exception or Error

Worth it also to discuss how to use forFeature on a standalone setup

provideStore() will be released soon.

EDIT: forFeature() discussion
