Loki Helm Chart document should support Helm 3 ?

[oke-py]

Is your feature request related to a problem? Please describe.
Helm 3 is GA now and some command options changed from v2.
For example, the command below fails.

$ helm install stable/grafana -n loki-grafana
Error: must either provide a name or specify --generate-name

Describe the solution you'd like
The document below should be updated.
https://github.com/grafana/loki/tree/master/production/helm

Describe alternatives you've considered
I'm not sure which of Helm v2 or v3 should be mainly supported.

Additional context

It works on Helm 3, the example fails because the -n argument was deprecated. Test this, it works for me:

helm install  loki-grafana stable/grafana
