Fix the path on loki helm install

[Waterdrips]

Missing a split on the "/" in chart name so we installed the chart as "loki/loki-stack" rather than loki.

Tested by removing all references to loki from my helm3 repo ls

then used `go build && ./arkade install loki" which worked.

Fixes #132

Please add a comment here to explain what is happening? This didn't seem to be necessary for any of the other apps? Why?

sorry i missed updating this before the PR was merged,

Its done so we can use 1 generic name in the new LokiOptions -> Heml -> Repo -> Name section.
All the other apps pass in just the chart name, not repo/chart - this is backward compatible as other apps pass in the chart section only.
