ng-add should also work for ESLint 9 flat config files

Which @ngrx/* package(s) are relevant/related to the feature request?

eslint-plugin

Information

Currently the NgRx eslint plugin only configures the NgRx plugin within a json file.
We should also add the option to configure our plugin within flat config files.

The schematic should automatically detect which file needs to be updated.
We can take a look at the Angular ESlint plugin for inspiration https://github.com/angular-eslint/angular-eslint/blob/390df5a211f7016be1bcc12c4e139796c1867867/packages/schematics/src/ng-add/index.ts#L41

@timdeschryver is it open for picking? I am willing to dive deep into the flat config.
