AWS cli documentation change
Summary
Updated AWS CLI version references from 2.34.61 to 2.34.63 and added documentation for HMAC key KCV computation method
Security assessment
The version update is routine maintenance. The added HMAC KCV computation documentation describes a security validation feature (key integrity checking) but doesn't indicate any vulnerability fix.
