i have recently upgraded the aks cluster to 1.26, in my cluster, I have used the 2.7.1 keda operator,in 1.26 v of Kubernetes cluster, hpa API version has been changed, so I have manually modified the scaled-object API version from keda.sh/v1alpha1 to keda.sh/v2beta2, but it is not worked, so I have deleted old keda and its resources,and also removed crd's respectively,when I tried to install to new keda version in cluster,it throws error (sigs.k8s.io/controller-runtime/pkg/cache/internal/informers_map.go:262: failed to list *v1alpha1.ScaledObject: request to convert CR from an invalid group/version: keda.sh/v2beta2) like this, i have uninstalled all previous resources properly,still it is showing v2beta2,please help me to resolve this
