Set both kibana.alert.url and context.alertDetailsUrl for observability alerts

📝 Summary

In v8.8, AO introduced the alert details page for APM Latency threshold and also added context.alertDetailsUrl to the action variables of that rule type here. (We are not using this variable in the default action message yet)

Now we want to add the same parameters to the other observability rule types (#156534), but since we already have kibana.alert.url, the question is whether to move forward with adding context.alertDetailsUrl to all the observability rule types or use kibana.alert.url instead.

After discussion with @XavierM , it seems providing kibana.alert.url as an action variable is complicated, and we might not be able to deliver it in v8.9. On the other hand, we want to ensure that observability users can navigate to a page filtered for that alert sooner.

@XavierM suggested that we continue using context.alertDetailsUrl until the work related to providing all alert fields in the action context is done and then think about a migration plan to update the existing action messages and replace context.alertDetailsUrl with kibana.alert.url. Also, we might need to consider to change the context mapping to a flattened field so our user does need to know what we define here and it will be more an internal sauce for our application.
