[Bug]: oci_python_image example does not copy correct prebuilt binaries
What happened?
See https://github.com/aspect-build/bazel-examples/compare/main...chulkilee:bazel-examples:oci-py-target?expand=1
This is to show how the current oci_python_image example does not work when building on macos.
cd oci_python_image
bazel run //hello_world:tarball
docker run --rm gcr.io/oci_python_hello_world:latest
Traceback (most recent call last):

ModuleNotFoundError: No module named 'pydantic_core._pydantic_core'
This is because pydantic_core's prebuilt is copied from host (macos), not for target. See the following output having darwin, not linux.
docker run --rm gcr.io/oci_python_hello_world:latest ls /hello_world/hello_world.runfiles/rules_python~~pip~pip_39_pydantic_core/site-packages/pydantic_core/
Output:
__init__.py
_pydantic_core.cpython-39-darwin.so
_pydantic_core.pyi
core_schema.py
py.typed
Interestingly, it actually did use the right python
docker run --rm gcr.io/oci_python_hello_world:latest ls /hello_world/hello_world.runfiles
Output:

Version
Development (host) and target OS/architectures:
Output of bazel --version: 7.3.0
Version of the Aspect rules, or other relevant rules from your
WORKSPACE or MODULE.bazel file: did not change from oci_python_image
Language(s) and/or frameworks involved: python
How to reproduce
See https://github.com/aspect-build/bazel-examples/compare/main...chulkilee:bazel-examples:oci-py-target?expand=1
Any other information?
It doesn't fail the test since apparently tests are running on linux machine.
