Inconsistency kafka example with messaging semconv

What's the problem?

Hi, I found out that the kafka example does not match the described standard in the messaging span kind section: messaging.operation.type doesn't match with message span kind in example.

Describe the solution you'd like

I suggest change span kind in the kafka example in accordance with messaging span kind docs.

Hi @geny200 can you clarify which span kind is not in accordance? Do you mean the "Span poll" one? I think you are right, it should be CLIENT, as the other examples like: https://github.com/dynatrace-oss-contrib/semantic-conventions/blob/main/docs/messaging/messaging-spans.md#batch-publishing-with-create-spans

[geny200]

I think it should be like this:

Field or Attribute	Consumer Span Poll	Consumer Span Process	Consumer Span Commit T
SpanKind	CLIENT	CONSUMER	CLIENT
messaging.operation.type	"receive"	"process"	"settle"

Because in table operation type - span kind:

Operation type	Span kind
receive	CLIENT
process	CONSUMER
settle	CLIENT

Right, thanks for reporting. I will send a PR to fix it, unless you want to do it :)

Ok, I'll do it)
