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

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

                                   syntax = "proto3";

                                   service Greeter {
                                     rpc SayHello (HelloRequest) returns (HelloReply);
                                   }

    // Arrange

    // Act

    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();
