Feedback: Install Redis Enterprise Helm chart

Page https://redis.io/docs/latest/operate/kubernetes/deployment/helm

We say "\<repo-name\>" instead of "redis" for the name of our Helm repo
```
helm repo add <repo-name> https://helm.redis.io
```

It should be
```
helm repo add redis https://helm.redis.io
```

As mentioned in: https://helm.redis.io/

The \<repo-name\> is also unnecessarily templated in the 2.) section below this, as well
