@dnskr thank you for the contribution , you'll need to run make generate-helm-docs to fix helm doc lint issue

I used helm-docs command directly, but it adds the following footer:

----------------------------------------------
Autogenerated from chart metadata using [helm-docs v1.11.0](https://github.com/norwoodj/helm-docs/releases/v1.11.0)

The command make generate-helm-docs generates expected output.
