Description of problem:

If you delete a pipelinerun then it will be deleted in the k8s cluster but the data will be available in the tekton-results database, so the pipeline run list view will show the deleted pipelineruns

Prerequisites (if any, like setup, operators/versions):

Openshift Pipelines operator should be installed
tektonResults should be installed and working in the cluster(Follow this https://gist.github.com/vikram-raj/257d672a38eb2159b0368eaed8f8970a)

Steps to Reproduce

1. Create pipeline runs
2. Delete a pipeline run

Actual results:

It endlessly shows pipeline run and mentions `Resource is being deleted` in kebab menu

Expected results:

Gracefully handle it like adding a hint to the user that the Delete action will only delete it from the etcd storage and disable the delete action for results-based PLRS

Reproducibility (Always/Intermittent/Only Once):

Always
