Bump grpc-go to 1.83.1 in dnsrocks

Summary: Upgrade google.golang.org/grpc from 1.82.1 to 1.83.1 in dnsrocks.

v1.83.1 raises the minimum versions of go.opentelemetry.io/otel/sdk/metric and google.golang.org/genproto/googleapis/rpc.

Running go get google.golang.org/grpc@v1.83.1 updates both;

leaving them unchanged causes Go to report that go.mod needs updates.
