Helm chart not maintained

[aottr]

What happened
The linked helm chart is not maintained anymore which limits the configuration of immudb. This prevents me from using e.g. the external storage on S3 etc.

What you expected to happen
Helm chart up to date with current version of immudb (Helm chart is generated for version 1.5.0)

I'd either advise to update the chart or remove it from the documentation / readme.
