title: Storybook 6 error: ngrx no provider for Store error - how to fix?
body: <p>My Angular10 application is working fine when using ng serve / nx serve.
  The NGRX store and Feature stores are working as expected.</p>
  <p>However, when I try and run a Storybook from any of my Libs in the project I get errors.
  Why is this? How do I fix this? I have not found a solution so far.</p>
  <p>This is part of the error:</p>
  <pre><code>StaticInjectorError(Platform: core)[InjectionToken @ngrx/store Check if Action types are unique -&gt; InjectionToken @ngrx/store Internal Runtime Checks]: 
      NullInjectorError: No provider for InjectionToken @ngrx/store Internal Runtime Checks!
  </code></pre>
  <p>Does anyone know a solution? Thanks.</p>
