Add helm repo update command to Kubernetes install docs
What does this MR do?
Adds the helm repo update gitlab
to the installation instructions for the Kubernetes executor.
Why was this MR needed?
In testing the k8s executor on GKE Autopilot, I noticed that adding the GitLab Helm repository via the helm repo add gitlab https://charts.gitlab.io
command did not result in the retrieval of the latest chart and Runner versions.
What's the best way to test this MR?
What are the relevant issue numbers?
