Describe the issue you're reporting

I am using honeycomb classic and OTEL v0.88 and I have been trying to set the dataset header using resource attribute service.name but its not working for me.

If I cant upgrade from honeycomb classic how would I in essence use the data in the processor to set the header in the exporter.

This is the code I have now:

exporters:
    otlp/k8s-metrics:
      headers:
        "x-honeycomb-team": "${env:HONEYCOMB_API_KEY}"
        "x-honeycomb-dataset": "${service.name}-metrics"

and

exporters:
    otlp/k8s-metrics:
      headers:
        "x-honeycomb-team": "${env:HONEYCOMB_API_KEY}"
        "x-honeycomb-dataset": "resource.attributes["service.name"]-metrics"

the second excerpt returns dataset as resource.attributes["service.name"]-metrics and the first one returns -metrics and therefore I cannot dynamically set the header.
