Fixed in 6ebf16b.

Root cause: Google.Protobuf 3.31.1 isn't NativeAOT-clean — RepeatedField<T>.TryGetArrayAsSpanPinnedUnsafe calls Marshal.SizeOf(Type), producing IL3050, which surfaced as error IL3053: Assembly 'Google.Protobuf' produced AOT analysis warnings and failed the dotnet publish --aot step of both tests.

The upstream fix (protocolbuffers/protobuf#21824) shipped in the 3.33.2 patch, so I bumped GoogleProtobufVersion to 3.33.6 (latest patch of that line). gRPC packages stay at 2.83.0, whose minimum Google.Protobuf requirement (3.31.1) is satisfied.

Validation:

• Reproduced the IL3050/IL3053 failure with 3.31.1 and confirmed a warning-free NativeAOT publish with 3.33.6 for a gRPC service generated by Grpc.Tools 2.83.0; the published native binary starts and serves.
• No public API removals between 3.31.1 and 3.33.6.
• ./src/Grpc/build.sh builds clean; JsonTranscoding unit tests (295) and integration tests (24) pass.
