fix: update loki helm chart repo

Grafana has deprecated their previous Helm chart repo and moved all of
their charts to https://grafana.github.io/helm-charts. The chart itself
has no breaking changes, therefore, this patch only requires changing
the Helm repo name and url.

It also updates the Loki docs URLs to link to the rendered Grafana docs
isntead of the doc source files on Github.
