[Actionable observability] Make the alert summary widget clickable

[maryam-saeidi]

📝 Summary

The alert summary widget should be clickable and upon clicking on the number of active or recovered alerts, the user will be redirected to a page with more information.

Questions:

1. Should this navigation be defined in the component or be provided by the consumer?
   It will be passed to the component by the consumer since we have different alert tabs for different apps.

✅ Acceptance Criteria

• Make the alert summary widget clickable

@maryam-saeidi Regarding Q1 where to redirect the user to when they click on the widget, given this component will be integrated in many different pages and contexts (and we can expect more to come in the future), I would recommend to allow the consumer/integrator to configure the redirect URL. A default can/should be provided though.

@emma-raffenne Yes, my question was before I was aware of having different alert tabs and I will add the possibility of providing a link by the consumer. (I will update the ticket description)
By default, it will not be clickable since the component cannot decide where to send the user with which type of filtering.
