šŸ› (go/v4,kustomize/v2): Fix problems by simplify scaffold and removing webhookcainjection_patch. Clarifying replacements for cert-manager (#4123)
fix issues by simplifying the scaffold. Removes webhookcainjection_patch and clarify replacements. - Removed config/default/webhookcainjection_patch.yaml to streamline the scaffold. - Clarified replacements blocks in kustomization.yaml for easier understanding. Each block is now labeled with instructions for uncommenting based on specific webhook scenarios (ValidatingWebhook, DefaultingWebhook, ConvertingWebhook).
