Move OTEL_RESOURCE_ATTRIBUTES to last position on env list.
When OTEL_RESOURCE_ATTRIBUTES environment variable uses other env vars as attributes value they have to be configured before. It is mandatory to set right order to avoid attributes with value pointing to the name of used environment variable instead of its value.

Correct order of env vars

env:
 - name: OTEL_RESOURCE_ATTRIBUTES_NODE_NAME
   valueFrom:
     fieldRef:
       fieldPath: spec.nodeName
 - name: OTEL_RESOURCE_ATTRIBUTES_POD_NAME
   valueFrom:
     fieldRef:
       fieldPath: metadata.name
 - name: OTEL_RESOURCE_ATTRIBUTES
   value: k8s.node.name=$(OTEL_RESOURCE_ATTRIBUTES_NODE_NAME),k8s.pod.name=$(OTEL_RESOURCE_ATTRIBUTES_POD_NAME)

This PR fixes: #793

Few nits, but the approach looks good. Also the CI failed.
