Fluent operator chart for v3.3.0 points to "latest" image tag instead of "v3.3.0"

See [here](https://github.com/fluent/helm-charts/blob/fluent-operator-3.3.0/charts/fluent-operator/values.yaml#L27). Previous releases [pointed to the correct tag](https://github.com/fluent/helm-charts/blob/fluent-operator-3.2.0/charts/fluent-operator/values.yaml#L27).

The "latest" tag is currently broken due to an operator bug, so this will break/is breaking installations.
