Chart version v0.4.10 not pullable with helm

[mardonner]

What happened?

Hi,
even though v0.4.10 of the helm chart was released here, the index.yaml file does not list that release. Therefore, it is not pullable by the helm cli.

How can we reproduce this?

helm version
version.BuildInfo{Version:"v4.2.0", GitCommit:"06468084e85c244c712834933d25ea232a4c2093", GitTreeState:"clean", GoVersion:"go1.26.3", KubeClientVersion:"v1.36"}
