salt: Re-render loki Salt formula

We have bump loki chart, so we need
to re-render this formula as follows:

```
./charts/render.py loki charts/loki.yaml charts/loki/ \
  --remove-manifest Secret loki \
  --namespace metalk8s-logging \
  --service-config loki metalk8s-loki-config \
                   metalk8s/addons/logging/loki/config/loki.yaml \
                   metalk8s-logging \
  > salt/metalk8s/addons/logging/loki/deployed/chart.sls
```
