[timdeschryver]

Information

The rule signal-store-feature-should-use-generic-type should be documented at https://github.com/ngrx/platform/blob/main/projects/ngrx.io/content/guide/eslint-plugin/rules/signal-store-feature-should-use-generic-type.md.

It should also contain one or more examples showcasing some "bad" and "good" snippets.

@timdeschryver see #4515 I've updated prefer-protected-state.md in that PR as well - I am not sure whether or not this is something acceptable to mix a little PR responibilities. Let me knwo - I can split it into two commits :)
