Note

Medium Risk
Telemetry behavior changes based on OTEL_SEMCONV_STABILITY_OPT_IN, potentially altering gRPC span attributes and RPC duration metric names/units and impacting dashboards/alerts; no core request handling logic is changed.

Overview
Updates go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc from v0.67.0 to v0.68.0 (including vendored code and checksums), plus a small google.golang.org/genproto/googleapis/rpc bump.

The new vendored otelgrpc adds semantic convention stability opt-in via OTEL_SEMCONV_STABILITY_OPT_IN, allowing rpc/old, rpc/dup, or default behavior to control whether gRPC spans/metrics use old, new, or duplicated RPC attributes and whether to emit old rpc.*.duration metrics (ms) alongside the newer rpc.*.call.duration metrics (s). It also adjusts where server address attributes are sourced in stats handling (using header/trailer addr fields instead of peer.FromContext).
