Isai df179f0ab1 [Rule Tuning] AWS STS GetCallerIdentity API Called for the First Time (#4995) ...

* [Rule Tuning] AWS STS GetCallerIdentity API Called for the First Time

Rule is executing as expected with no troubling alerts in telemetry. For tuning I've:

- reduced the execution window
- removed MD from description and FP as it's not supported in Kibana UI
- edited some of the language of IG to speak about the exclusion of AssumedRoles
- edited the highlighted fields for consistency across AWS rules

* updated broken link

updated broken reference link
