[tidy first] generate protos w protoc version 5.26.1

[MichelleArk]

resolves #10457

Problem

Currently types_pb2.py is generated using protoc version 4.25.3. It looks like the latest compatible version of protoc that doesn't need any code changes (indicated by failing tests is 5.26.1).

Solution

generate core_types_pb2.py with protoc version 5.26.1
