splunkhecexporter: migrate to newer semconv version (#35391)

Description: The version of semconv is upgraded from v1.6.1 to v1.27.0

This is a trivial upgrade. The semconv attributes' value have been
compared using
[go-otel-semconv-comparator](https://github.com/narcis96/go-otel-semconv-comparator).
All attributes used by this component have the same value in both
versions.

#22095
