[Feature Request]: Protobuf 5+ support

[steerlink]

What would you like to happen?

Is it possible for the python sdk and image to support protobuf 5+?

I have a project that consumes protobuf files generated with version 5.27 of protoc. Those files introduce the following import which isn't understood by protobuf 4.26.0.

from google.protobuf import runtime_version as _runtime_version
