Hello Kubernetes tutorial should use the Helm installation instead of the dapr init -k approach

Looking at this tutorial: https://github.com/dapr/quickstarts/tree/master/tutorials/hello-kubernetes , as a Kubernetes user I get scared of using a new CLI to install tools. I recommend switching to installing Dapr using Helm, a mechanism much more familiar to Kubernetes user.

This means changing `dapr init -k --dev` for the following commands:

Install Dapr
```
helm repo add dapr https://dapr.github.io/helm-charts/
helm repo update
helm upgrade --install dapr dapr/dapr \
--version=1.13.2 \
--namespace dapr-system \
--create-namespace \
--wait
```

To install Redis:

```shell
helm install redis oci://registry-1.docker.io/bitnamicharts/redis --version 17.11.3 --set "architecture=standalone" --set "master.persistence.size=1Gi"
```

If `dapr init -k --dev` is installing more things, for Kubernetes audience we need to make them explicit. Nobody likes installing things on a cluster without knowing exactly what is going on, it makes it more difficult to troubleshoot.
