ProtoBufMatcher not working when proto package name contains dots

[vgoranski]

Describe the bug

When I'm trying to use the recently introduced ProtoBufMatcher with package in proto that contains dots in the name, I'm getting Grpc.Core.RpcException with message Status(StatusCode="Unimplemented", Detail="Bad gRPC response. HTTP status code: 404"). If I remove the dots everything works fine.

Expected behavior:

Package name containig dots works.

Test to reproduce

public async Task WireMockServer_WithBodyAsProtoBuf_InlineProtoDefinition_UsingGrpcGeneratedClient()
{
    const string packageName = "greet.foo";
    const string protoDefinition = $$"""

                                   syntax = "proto3";
                                   package {{packageName}};
                                   service Greeter {
                                     rpc SayHello (HelloRequest) returns (HelloReply);
                                   }
                                   message HelloRequest {
                                     string name = 1;
                                   }
                                   message HelloReply {

                                   }

                                   """;

    // Arrange
    using var server = WireMockServer.Start(useHttp2: true);

    var jsonMatcher = new JsonMatcher(new { name = "stef" });

    server
        .Given(Request.Create()
                      .UsingPost()
                      .WithPath($"/{packageName}.Greeter/SayHello")
                      .WithBodyAsProtoBuf(protoDefinition, $"{packageName}.HelloRequest", jsonMatcher)
        )
        .RespondWith(Response.Create()
                             .WithHeader("Content-Type", "application/grpc")
                             .WithTrailingHeader("grpc-status", "0")
                             .WithBodyAsProtoBuf(protoDefinition, $"{packageName}.HelloReply",
                                 new
                                 {
                                     message = "hello stef {{request.method}}"
                                 }
                             )
                             .WithTransformer()
        );

    // Act
    var channel = GrpcChannel.ForAddress(server.Url!);

    var client = new Greeter.GreeterClient(channel);

    var reply = await client.SayHelloAsync(new HelloRequest { Name = "stef" });

    // Assert
    reply.Message.Should().Be("hello stef POST");

    server.Stop();
}
