🐞 bug report

Description

I upgraded Bazel to use rules_python 0.39.0 -> all the tests pass.
I removed python providers from Bazel -> smoke tests started failing.

🔬 Minimal Reproduction

Checkout bazelbuild/bazel#24343
bazel build //src/test/shell/bazel:bazel_example_test --test_filter=test_native_python

Example in: https://github.com/bazelbuild/bazel/blob/master/examples/py_native/bin.py

-- Test log: -----------------------------------------------------------
Traceback (most recent call last):
  File "/tmp/Bazel.runfiles_vczmqfyg/runfiles/_main/examples/py_native/bin.py", line 4, in 
    from fib import Fib
ModuleNotFoundError: No module named 'fib'

My thoughs

It looks like that part of information was in Builtin providers that now gets lost.
