Platform: Docs for router-store has wrong config

[wszgrcy]

Other information:

code in platform/docs/router-store/api.md

interface StoreRouterConfig {
  stateKey?: string;
  serializer?: new (...args: any[]) => RouterStateSerializer;
  navigationActionTiming?: NavigationActionTiming;
}

but in "@ngrx/router-store": "^6.1.0",

export interface StoreRouterConfig {
    stateKey?: string;
}
export declare type StoreRouterConfigFunction = () => StoreRouterConfig;

I have not used before

I would be willing to submit a PR for the docs :heart:

This will become available in the next version.
To use it now you can install ngrx from the nightly builds.

I think it is confusing, as it is not present on main package but referenced on the main documentation. At least an explanation pointing that to use it ngrx router nightly builds is needed, could avoid misunderstandings.
