The only minor change is needed to make optional attributes for the error metric

Excludes error.type for successful responses by setting it to an empty string ("") and filtering it out during attribute collection.

Hm I think we agreed that for optional labels, we should use Scala's Option. That's much better than magic strings

Does we need to account Option[String] for Zio Metrics ig it may account for other metrics too?

Or better strategy to move this logic to OpenTelemetry module and introduce option labels than affecting other modules

that's fine, let's just have optional labels. This might be useful for ZIO as well
