feat: (IAC-1047) Update to newer release for cluster-autoscaler in EKS

[dhoucgitter]

Changes

• Update the default CLUSTER_AUTOSCALER_CHART_VERSION documentation to indicate that a helm chartVersion of 9.29.1 will be used for EKS Kubernetes clusters whose version is >= 1.25
• Update the chartVersion value to 9.29.1 that will be used for Kubernetes clusters using versions 1.25 or later
• Remove the appVersion value from the CLUSTER_AUTOSCALER_CONFIG for the latest autoScalerVersions entry, Thomas advised that it can be misleading to provide an appVersion since the appVersion field is informational only and has no impact on the chart version calculations.

Tests

Scenario	Provider	kubernetes_version	cluster-autoscaler chart version	cluster-autoscaler application Version	order	cadence	notes
1	AWS	1.26 (v1.26.7-eks)	9.29.1	1.27.2	n/a	n/a	iac-aws apply created cluster with min_node=1 for each worker node group. Stopped the single CAS node instance, the autoscaler restarted a new one to replace it within a few minutes, see PNG screen captures in the scenario1 folder of the IAC-1047.zip file
2	AWS	1.26 (v1.26.7-eks)	9.29.1	1.27.2	n/a	n/a	iac-aws apply created cluster with min_node=3 for the stateless node group. 3 stateless nodes were created as indicated. Stopped 2 stateless node instances, as each stateless node moved to the fully terminated state, the autoscaler created a new node to replace the terminated node within a few minutes, see PNG screen captures in the scenario2 folder of the IAC-1047.zip file
