Please make it work with protobuf editions

[EugenDueck]

I have a file like

edition = "2023";
...

When running protoc-gen-doc like so:

docker run --rm \
  -v $(pwd)/:/out \
  -v $(pwd)/proto:/protos \
  pseudomuto/protoc-gen-doc --doc_opt=markdown,proto-docs.md

It defaults to proto2, leading to many subsequent errors:

[libprotobuf WARNING google/protobuf/compiler/parser.cc:649] No syntax specified for the proto file: echo.proto. Please use 'syntax = "proto2";' or 'syntax = "proto3";' to specify a syntax version. (Defaulted to proto2 syntax.)

I would guess the protobuf dep would need to be updated. https://github.com/pseudomuto/protokit/blob/dc6fd1c8003a61bcd77ddc148e4d49946fbf8c23/go.sum#L3

yes please support editon = "2023";

@community are there any alternative documentation plugins that support it?

[abarke]

Failure: plugin "buf.build/community/pseudomuto-doc:v1.5.1" does not support feature "supports editions" which is required by "myproto/v1/myproto.proto"

Hello. If this issue still actual for you, please check solution from PR that I sent.

Thanks a lot, fedor-romanovskii! That said, we've long since switched back to proto3 for other reasons.
