Add helm documentation Docker image to helm-www repo

[tomerle03]

Hi,
I am working in an air gapped environment and I've wanted to deploy this docs so I made a docker image that's serve this docs in port 8080:

docker.io/tomerle03/helm-www:v3.14.4

I hope we can collaborate and you will add this image to your repo README.

I do not think this is a good idea. I think this issue should be closed in favor of your other issue #1591
