Update README with reference to helm repository and publish newest wiremock-0.1.4 version to the repo

[marcules]

Hi,

I've seen that, if I try to use this helm-chart with the helm-repo functionality helm repo add wiremock https://wiremock.github.io/helm-charts then the old repository at https://gitkent.github.io/helm-charts is referenced, which returns a 404 when trying to pull the chart from there. Further I've seen that version 0.1.4 was released on github but the index.yaml was not updated - so I've fixed the reference and ran publish-helm-chart.sh to update it.

Kind Regards, Marc
