Possible official support for `pyi` files generated in rules_proto_grpc_python?

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:

• #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 #295, sjportalatin submitted #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
