pipy dependency generated py_library ignores .pyc files in installed package.

🐞 bug report

Affected Rule

https://github.com/bazelbuild/rules_python/blob/main/docs/pypi-dependencies.md
Specifically py_library with name = "pkg" generated by

pip = use_extension("@rules_python//python/extensions:pip.bzl", "pip")
pip.parse(
    hub_name = "my_deps",
    python_version = "3.11",
    requirements_lock = "//:requirements_lock_3_11.txt",
)
use_repo(pip, "my_deps")

Is this a regression?

I don't know.

Description

I couldn't import a module from pip package that ships python modules with .pyi and .pyc files.
For example, I have a example_package that ships with the following file structure

/example_package
  __init__.py
  foo.pyc
  foo.pyi

According to https://peps.python.org/pep-3147/#flow-chart,

import foo from example_package

Should be successful. But the py_library generated specifically excludes "**/*.pyc" from data. If I manually remove the "**/*.pyc" exclusion, the import statement works.

py_library(
    name = "pkg",
    srcs = glob(
        ["site-packages/**/*.py"],
        exclude=[],
        # Empty sources are allowed to support wheels that don't have any
        # pure-Python code, e.g. pymssql, which is written in Cython.
        allow_empty = True,
    ),
    data = [] + glob(
        ["site-packages/**/*"],
        exclude=["**/* *", "**/*.py", "**/*.pyc", "**/*.pyc.*", "**/*.dist-info/RECORD"],
    ),
    # This makes this directory a top-level in the python import
    # search path for anything that depends on this.
    imports = ["site-packages"],
    deps = [],
    tags = ["pypi_name=example_package", "pypi_version=3.21.0"],
    visibility = ["//visibility:public"],
)

How

🔬 Minimal Reproduction

1. Creating a pip package following https://packaging.python.org/en/latest/ but replace the foo.py with compiled foo.pyc file.
2. Add pip dependency to a bazel workspace following guides in https://github.com/bazelbuild/rules_python/blob/main/docs/pypi-dependencies.md
3. In a py_library or py_binary, import foo from example_package should work but errors out with module not found error.

🔥 Exception or Error

ImportError: cannot import name 'foo' from 'example_package'
