Changes

protovalidate: support new protovalidate-go Validator interface.

Verification

protovalidate-go v0.9 release said:

protovalidate.Validator is now an intkerface and not a struct. Pointers of type *protovalidate.Validator should be changed to protovalidate.Validator values instead.

 Additional great feature of interceptors is the fact we can chain those. For example below you can find example server side chain of interceptors with full observabiliy correlation, auth and panic recovery:
 
 ```go mdox-exec="sed -n '136,151p' examples/server/main.go"
-	grpcSrv := grpc.NewServer(
-		grpc.ChainUnaryInterceptor(
-			// Order matters e.g. tracing interceptor have to create span first for the later exemplars to work.
-			otelgrpc.UnaryServerInterceptor(),
-			srvMetrics.UnaryServerInterceptor(grpcprom.WithExemplarFromContext(exemplarFromContext)),
-			logging.UnaryServerInterceptor(interceptorLogger(rpcLogger), logging.WithFieldsFromContext(logTraceID)),
-			selector.UnaryServerInterceptor(auth.UnaryServerInterceptor(authFn), selector.MatchFunc(allButHealthZ)),
-			recovery.UnaryServerInterceptor(recovery.WithRecoveryHandler(grpcPanicRecoveryHandler)),
-		),
-		grpc.ChainStreamInterceptor(
-			otelgrpc.StreamServerInterceptor(),
-			srvMetrics.StreamServerInterceptor(grpcprom.WithExemplarFromContext(exemplarFromContext)),
-			logging.StreamServerInterceptor(interceptorLogger(rpcLogger), logging.WithFieldsFromContext(logTraceID)),
-			selector.StreamServerInterceptor(auth.StreamServerInterceptor(authFn), selector.MatchFunc(allButHealthZ)),
-			recovery.StreamServerInterceptor(recovery.WithRecoveryHandler(grpcPanicRecoveryHandler)),
-		),
+	)
+	t := &testpb.TestPingService{}
+	testpb.RegisterTestServiceServer(grpcSrv, t)
+	srvMetrics.InitializeMetrics(grpcSrv)
+
+	g := &run.Group{}
+	g.Add(func() error {
+		l, err := net.Listen("tcp", grpcAddr)
+		if err != nil {
+			return err
+		}
+		logger.Info("starting gRPC server", "addr", l.Addr().String())
+		return grpcSrv.Serve(l)
+	}, func(err error) {
+		grpcSrv.GracefulStop()
+		grpcSrv.Stop()

This pattern offers clean and explicit shared functionality for all your gRPC methods. Full, buildable examples can be found in examples directory.

Would love to get this version upgrade merged as it's blocking package upgrades on our projects. protovalidate-go v0.8 and v0.9 broke compatibility, and was fixed with v0.9.1. bufbuild/protovalidate-go#180 (comment)
