AWS Role Assumption By User
This rule seem fine in telemetry and the rule executes as expected
- removed MD from description
- fixed inaccuracies in Investigation Guide
- added Lateral Movement tag
- adjusted highlighted fields
- added `cloud.account.id` to new_terms field to account for duplicate user.names across cloud accounts
- replaced new terms flattened field for `aws.cloudtrail.resources.arn`, which gives the same result and remains consistent with the other rule.
