[FR]: Move away from rules_proto?

[antspy]

What is the current behavior?

Hi,

The rules_proto is now deprecated in favour of protobuf. While one can use the proto_library from protobuf instead of rules_proto (i.e. do load("@protobuf//bazel:proto_library.bzl", "proto_library") instead of load("@rules_proto//proto:defs.bzl","proto_library")), there doesn't seem to be an equivalent for the proto_lang_toolchain macro.

Describe the feature

I am not sure if the proto_lang_toolchain is still needed or what would be the solution, but I guess we might have to move away from rules_proto at some point :)
