FileDescriptorProto ambiguity after upgrading to >=2.5.0 version

[MiguelCosta]

Description

We are trying to upgrade KafkaFlow to the most recent Confluent.Kafka.* packages.

At this moment, KafkaFlow is using version 2.1.1, we can upgrade to version 2.4.0 without any issue, but if we update to the most recent version (>=2.5.0) we have this error:

Error CS0433 : The type 'FileDescriptorProto' exists in both 'Google.Protobuf, Version=3.26.1.0, Culture=neutral, PublicKeyToken=a7d26565bac4d604' 
and 'protobuf-net.Reflection, Version=3.0.0.0, Culture=neutral, PublicKeyToken=257b51d87d2e4d67'

Version 2.5.0 introduces the package protobuf-net.Reflection

Because of this change, Confluent.SchemaRegistry.Serdes.Protobuf package uses different libraries with the same class name and namespace (Google.Protobuf.Reflection.FileDescriptorProto)

• Google.Protobuf https://github.com/protocolbuffers/protobuf/blob/main/csharp/src/Google.Protobuf/Reflection/FileDescriptor.cs
• protobuf-net.Reflection package: https://github.com/protobuf-net/protobuf-net/blob/main/src/protobuf-net.Reflection/google/protobuf/descriptor.proto#L47

Steps to reproduce

• Fork https://github.com/Farfetch/kafkaflow
• Upgrade to Confluent.Kafka.* packages to >=2.5.0
• Compile csproj KafkaFlow.Serializer.SchemaRegistry.ConfluentProtobuf
