fix: Auto Mode custom tag policy should apply to cluster role, not node role

[bryantbiggs]

Description

• Auto Mode custom tag policy should apply to cluster role, not node role

Motivation and Context

• Currently this is incorrect per https://docs.aws.amazon.com/eks/latest/userguide/auto-learn-iam.html#tag-prop and therefore instances fail to provision when custom tags are applied to a node class

Breaking Changes

• Claiming this as a no since it never worked as intended. Yes, the policy will be destroyed and permissions removed from the node but those permissions were not being used for anything - they need to be applied to the cluster role
