What happened?

Description

I want to set "service.name" and "service.version" from the env variables, in the transform processor pipeline. I have tried this.

- set(resource.attributes["service.name"], ${env:OTEL_SERVICE_NAME}) where resource.attributes["service.name"] == nil
- set(resource.attributes["service.version"], ${env:OTEL_SERVICE_VERSION}) where resource.attributes["service.version"] == nil

Can someone either point me to a doc mentioning the same or give an example of how to use the env variables inside the set().

Regards
