chore(telemetry): fix protocol in otel metrics (#15010)

mabdinur · mabdinur · commit b47ea5c05be0 · 2025-10-23T14:06:19.000-04:00
Protocol is currently set as "http/protobuf", it should be sent as "http". This PR fixes this. This regression was found via system tests. We do not need additional testing. (cherry picked from commit 5fa0681)
