update to support protobuf editions

[zwing99]

edition = "2023";

message TestContract {
    string id = 1;
    string name_of_person = 2;
    int32 age = 3;
}

using the contract above i get this warning:

test_contracts.proto: is an editions file, but code generator protoc-gen-mypy hasn't been updated to support editions yet. Please ask the owner of this code generator to add support or switch back to proto2/proto3.

Editions seems like the go forward for protobuf and mypy is certainly the go forward for python. Any chance this tooling can be updated to support it?

+1 on this. Editions are the future of Protobuf, will be very helpful to have this for strong types.

yep seems reasonable! I've definitely been a bit behind in doing updates.

Let me catch some time in between things at my startup. Bear with me.

Thank you — as a note, I was able to get up and running with the official protocolbuffers/pyi package. They may have a reference implementation
