Allow searching CRDs

### What would you like to be added? When searching for something in kubernetes dashboard UI, if you search for a CRD like `PrometheusRule`, or even the name of a specific CRD like `kafka-cluster`, it will not show it. The only way to view CRDs is to manually click on the Custom Resource Definitions tab in the bottom left and scroll through all of the installed CRDs to find the one you are interested in. ### Why is this needed? Major QoL improvement. Being able to search for CRDs would make certain workflows much easier to perform as searching through the list of many CRDs just to find the one I want is not ideal.
