Generate helm-docs readme for all charts

[Allex1]

@TylerHelmuth @dmitryax I was thinking to add helm-docs for all of our chart like Grafana charts have for example. We use them in all charts and I find it very useful. I can also add contributing instructions for users to keep them in sync when they make changes in values.yaml. WDYT ?

[dmitryax]

Sounds good to me 👍

[TylerHelmuth]

Agreed. Id say we should add something to the workflows that enforces things stay in sync, like we do with examples.

@TylerHelmuth , Can you confirm whether this enhancement requirement is still open ?

[TylerHelmuth]

Yes this would still be helpful

@Allex1 / @TylerHelmuth , Can you elaborate more on the issue and I am new to open source so it would be really helpful if you provide me some guide regarding changes.
Can you please assign it to me?
