Metrics-server Helm chart 3.13.1 release exists but is missing from Helm repo index

[andytael]

What happened?

The GitHub release metrics-server-helm-chart-3.13.1 appears to exist, but the public Helm repository index at:

https://kubernetes-sigs.github.io/metrics-server/index.yaml

does not advertise chart version 3.13.1.

After refreshing the Helm repo, helm search repo only shows 3.13.0 as the latest chart version.

Commands run

helm repo add metrics-server https://kubernetes-sigs.github.io/metrics-server/
helm repo update metrics-server
helm search repo metrics-server/metrics-server --versions | head

Observed output:

NAME                          CHART VERSION  APP VERSION
metrics-server/metrics-server 3.13.0         0.8.0
metrics-server/metrics-server 3.12.2         0.7.2
metrics-server/metrics-server 3.12.1         0.7.1

## Expected behavior

The Helm repository index should include chart version 3.13.1, matching the GitHub release metrics-server-helm-chart-3.13.1.

## Why this matters

Projects that pin metrics-server chart 3.13.1 cannot reproduce dependencies with:

helm dependency update
helm dependency build

because Helm resolves chart dependencies from the repository index, not only from GitHub releases.
