Is your feature request related to a problem or use-case? Please describe.

We shipped Shipwright Build v0.12.0 with a cluster role and a binding for the webhook that are unnecessary. To follow least-privilege principle, we removed them in https://github.com/shipwright-io/build/pull/1448.

The operator must handle the deletion.

Describe the solution that you would like.

When updating v0.13.0, the operator should delete the clusterrole shipwright-build-webhook and the clusterrolebinding shipwright-build-webhook.

Describe alternatives you have considered.
