Update Protobuf Dependency

[sjoerdvandenbos-prodrive]

seldon-core sets an upper limit of its dependency of protobuf to < 4.0.0. Inspection of pipdeptree -p seldon-core shows that there is no subdependency that is causing this.

In order to improve developer experience I would like to generate type stubs for protobuf objects, however this is only possible starting from major version 4.

Is it possible to lift this restriction to for example protobuf < 5.0.0?

pipdeptree output:
