Missing Assembly Reference error with csharp_grpc_library

[plule]

Hello,

When building a  csharp_grpc_library, I get the error:

error CS0234: The type or namespace name 'BindServiceMethodAttribute'
does not exist in the namespace 'Grpc.Core' (are you missing an assembly reference?)

BindServiceMethodAttribute seems to be part of the Grpc.Core.Api assembly which is not included in csharp/nuget/nuget.bzl. It might be an issue with the script generating this file.

Here is a repository to reproduce the issue:
