salt: Re-render fluent-bit Salt formula

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

```
./charts/render.py fluent-bit --namespace metalk8s-logging \
  --remove-manifest ConfigMap fluent-bit \
  charts/fluent-bit.yaml charts/fluent-bit/ \
  > salt/metalk8s/addons/logging/fluent-bit/deployed/chart.sls
```
