…fabric-protos-go to fabric-protos-go-apiv2 and "github.com/golang/protobuf"(deprecated) to "google.golang.org/protobuf

Bumped google.golang.org/protobuf to v1.31.0 from v1.5.2

It can be noticed that the package "github.com/golang/protobuf" is still an indirect dependency used by google.golang.org/grpc/credentials v1.53.0, even the latest update v1.58.0 still does.

Made sure all tests passed.

CHANGES INCLUDE:

	SOURCE CODE
The "AssertProtoEqual" was borrowed from: // https://github.com/hyperledger/fabric-gateway/blob/cd1bc1f3fcf007bd97244120d9a8d112153322cd/pkg/internal/test/transaction.go#L20-L22
which is more apt to test the Protobufs of google.golang.org/protobuf/ implementation. It replaced assertEqual.
