[Bug]: grpc artifacts cannot be imported

[qdii]

What happened?

I made a minimum repro in a git repository to illustrate the issue:

Steps to reproduce:

1. git clone https://github.com/qdii/aspect_py_grpc.git
2. cd aspect_py_grpc
3. bazel run //mm:user_factory.venv
4. pyright --verbose

What is happening:
The line: Could not import 'mm.user_pb2' in file '/home/qdii/dev/aspect_py_grpc/mm/user_factory.py' appears.

What should have happened:
The user_pb2.py file should have been found.

Version

Development (host) and target OS/architectures: Arch Linux / x64

Output of bazel --version: 8.4.1

Version of the Aspect rules, or other relevant rules from your
WORKSPACE or MODULE.bazel file: 1.6.3

Language(s) and/or frameworks involved: Python 3.12

How to reproduce

Any other information?

pyright uses pyproject.toml to determine which venv to use.

In the repository's pyproject.toml, venv points to the virtual environment generated by aspect's rules_py.

pyright should be able to find the python file produced by the compilation of the proto file, but does not.
