Isai 8c5231ec4e [Rule Tuning] AWS RDS DB Snapshot Shared with Another Account (#5418) ...

This rule is performing well in telemetry and producing alerts as expected for both explicit external account sharing and making snapshots public. Both scenarios tested.
- updated description, FP and IG
- added highlighted fields
- added `event.type` as `event_category_override` field because `event.category` is not populated for these events.
