When using ACM CRs to template a policy, PolicyGenerator fails with the error:

{ComparisonError Failed to load target state: failed to generate manifest for source 1 of 1: rpc error: code = Unknown desc = Manifest generation error (cached): `kustomize build <path to cached source>/policygentemplates/ztp-test/acm-crs --enable-alpha-plugins` failed exit status 1: /.config/kustomize/plugin/policy.open-cluster-management.io/v1/policygenerator/PolicyGenerator: /lib64/libc.so.6: version `GLIBC_2.32' not found (required by /.config/kustomize/plugin/policy.open-cluster-management.io/v1/policygenerator/PolicyGenerator)
