[Response Ops][Cases] Fix alerts tab in cases detail page (#208672)

## Summary

Closes https://github.com/elastic/kibana/issues/208290

Rollback `includeComments` in `resolve` case endpoint to fix the alerts
tab in cases detail page. I'll create a new issue to use an alternative
approach to get the data needed by the alerts tab.

#### To do (might be shipped after FF):
- [ ] Test the alert tab shows the right amount of alerts in header
- [ ] Test the alert tab shows the alerts in content table

### QA
- Create alerts in security
- Add an alert to a case
- Check:
<details>
<summary>that number of alerts isn't 0 and the alert commet in activity
list exist</summary>
