Thanks for the PR 👍 few comments needs addressing.

1. Add this to complete addon example. Show some examples of how to use Kyverno with policies

we will need to:

1. Update the version of Kyverno here https://github.com/aws-samples/eks-blueprints-add-ons/blob/main/add-ons/kyverno/Chart.yaml#L19
2. Add an enable flag for the policies and reporter
3. Add policies and reporter dependencies to https://github.com/aws-samples/eks-blueprints-add-ons/blob/main/add-ons/kyverno/Chart.yaml#L17 similar to what was done here https://github.com/kyverno/policy-reporter/blob/main/charts/policy-reporter/Chart.yaml#L18
4. Update https://github.com/aws-samples/eks-blueprints-add-ons/blob/main/chart/values.yaml to match
