AUTOSCALE-827: apply KarpenterOperator feature gate to manifests

[maxcao13]

We replace the DevPreviewNoUpgrade featureset with the now merged KarpenterOperator feature gate which is only enabled in DevPreview clusters.

Summary by CodeRabbit

• Chores
  • Updated OpenShift release annotations across install and RBAC manifests to use the newer feature-gate value for Karpenter.
  • Aligned namespace, credentials, deployment, and cluster operator metadata with the same release gating setting.
  • No workload behavior, permissions, or deployment logic changed.

Walkthrough

This PR replaces the OpenShift release-gating annotation release.openshift.io/feature-set: DevPreviewNoUpgrade with release.openshift.io/feature-gate: KarpenterOperator across all install manifests (namespace, credentials request, RBAC, deployment, clusterrole, clusteroperator) and updates the hack/manifest-diff.sh stamping script to generate this new annotation.

Changes

Feature-gate annotation migration

Layer / File(s)	Summary
Manifest stamping script update hack/manifest-diff.sh	Introduces CVO_FEATURE_GATE="KarpenterOperator" and updates the stamping query to write release.openshift.io/feature-gate instead of release.openshift.io/feature-set.
Core resource manifests annotation update install/00_namespace.yaml, install/00_credentials-request-aws.yaml, install/03_aggregate-clusterrole.yaml, install/05_deployment.yaml, install/06_clusteroperator.yaml	Each manifest's metadata annotations switch from release.openshift.io/feature-set: DevPreviewNoUpgrade to release.openshift.io/feature-gate: KarpenterOperator.
RBAC resources annotation update install/04_rbac.yaml	All ServiceAccount, Role, RoleBinding, ClusterRole, and ClusterRoleBinding resources for karpenter-operator, karpenter-dns, and karpenter-operator-operand update their annotations to release.openshift.io/feature-gate: KarpenterOperator.

This requires us to apply the feature gate in the release repo job configs for e2e-aws and e2e-aws-operator. That release PR will block this PR.
