Fix namespace delete command in cleanup-helm-release.sh script (#5)
### Motivation

While making use of the scripts provided in this repo to prepare helm releases, I noticed that providing the ```-d``` flag (delete namespace) for the ```./scripts/pulsar/cleanup_helm_release.sh``` would always fail claiming that the **namespace already exists**. Upon closer examination, I noticed that the kubectl command to delete the provided namespace is actually attempting to create it instead.

### Modifications

I've gone ahead and made the corresponding modification on the script to delete the namespace (went from ```kubectl create namespace ${namespace}``` to ```kubectl delete namespace ${namespace}```).

### Verifying this change

I'm not sure what possible verifications I can provide for this PR. Please advise.
