Helm Chart Docs: global.tolerations should be array [] and not object {}

[avo-sepp]

Kubernetes Tolerations are represented as an array, example:

tolerations:
- key: "key1"
  operator: "Equal"
  value: "value1"
  effect: "NoSchedule"

The Helm chart for Dapr Operator only uses toYaml to bring in the values from values.yaml, there is no processing of an object.

{{- if .Values.global.tolerations }}
      tolerations:
{{ toYaml .Values.global.tolerations | indent 8 }}
{{- end }}

I think mapping from Object to Array works, I have not confirmed, but it is confusing from a documentation standpoint to see object {} in the README.md when I would expect array []
