Publish Helm Chart at Artifact Hub

**Is your feature request related to a problem? Please describe.**

Currently, the Helm Chart mentioned at Artifact Hub is missing at Artifact Hub https://artifacthub.io/

**Describe the solution you'd like**

It would be great to publish Helm Chart at Artifact Hub, thanks! ☺️

**Additional context**

There is an unofficial Helm chart at https://artifacthub.io/packages/helm/inseefrlab/label-studio and I saw a lot of people download the unofficial version based on the traffic.
