* [Rule Tunings] AWS SSM Command Document Created by Rare User

## AWS SSM Command Document Created by Rare User
Rule executes as expected and has very few alerts in telemetry. However, it is one of the rules timing out occasionally.
- reduced execution window
- reduced new terms history window
- replaced wildcards with the flattened field in the query, which should improve performance
- replaced `aws.cloudtrail.user_identity.arn` with combination of `cloud.account.id` and `user.name` to account for Assumed Roles. This will only evaluate the role instead of each individual role session, which will improve performance.
- added investigation fields
- corrected tags
- added mitre technique
