Possible official support for pyi files generated in rules_proto_grpc_python?

[planeyang]

Description

Hi,

I wonder if the maintainer of this project would kindly consider support pyi files generation for rules_proto_grpc_python.

Here are some prior arts:

• How to properly setup pyi_out dir in extra_protoc_args? #295 asked about how to generate pyi file but quickly closed the issue afterwards because they found a workaround. the workaround was "hacky" according to the original author, and needed users to reimplement the rules.
• from How to properly setup pyi_out dir in extra_protoc_args? #295, sjportalatin submitted [python] Generate .pyi stubs by default for .proto #352, which implemented the solution, but the PR hasn't been reviewed since Aug 30th.
• grpc library has added pyi support in 2023/Jun

Is there anything we can help from the user side to push this forward?

Thank you

Shout out to this nice blog post that references this issue. If anyone is trying to use pyi generation ahead of the next official release, this snippet will handle the fact that the repo has multiple modules and a dependency between them.
