[v2] Use only version number for BuildInfo

[yurishkuro]

Which problem is this PR solving?

We were passing the whole VersionInfo to OTEL's BuildInfo, which resulted in the metrics being labeled with a very long string: service_version="git-commit=600d82c5815289ba13197ce80b742c0f4411df78, git-version=v2.0.0, build-date=2024-11-26T15:15:15Z"

Description of the changes

Only pass the actual version. The metrics become much more readable: jaeger_query_responses_count{operation="get_services",service_instance_id="06f22e3e-3ad7-4067-8b0f-15d35b329712",service_name="jaeger",service_version="v2.0.0"}

How was this change tested?

$ curl -s http://localhost:8888/metrics | grep -v '^#' | grep 'get_services'
