with "confidentialCompute: Enabled" settings, the error message complains about "AMDEncryptedVirtualization" rather than "Enabled"

    see the build https://prow.ci.openshift.org/view/gs/test-platform-results/logs/release-openshift-origin-installer-launch-aws-modern/1917089506457030656 having the PR https://github.com/openshift/installer/pull/9637

    Always

    1. "create install-config", and then insert the interested settings (see [1])
    2. "create manifests" (or "create cluster", see [2])    

    With "confidentialCompute: Enabled" settings for both compute and controlPlane, the shown error message complains about confidential computing type "AMDEncryptedVirtualization", rather than "Enabled".

controlPlane.platform.gcp.type: Invalid value: "n2-standard-4": Machine type do not support AMDEncryptedVirtualization. Machine types supporting AMDEncryptedVirtualization: c2d, n2d, c3d, compute[0].platform.gcp.type: Invalid value: "n2-standard-4": Machine type do not support AMDEncryptedVirtualization. Machine types supporting AMDEncryptedVirtualization: c2d, n2d, c3d

    The expected error message is like, 

controlPlane.platform.gcp.type: Invalid value: "n2-standard-4": Machine type do not support Enabled. Machine types supporting Enabled: c2d, n2d, c3d, compute[0].platform.gcp.type: Invalid value: "n2-standard-4": Machine type do not support Enabled. Machine types supporting Enabled: c2d, n2d, c3d
