Windows + Bazel 8 gets permission denied error in some configs

Just filing a quick issue for now with some light details and investigation results

When run on BCR, we get a failure in the bzlmod example `//tests:version_test_binary_*` tests. It only fails for Windows and bazel 8.

example error:

```
Executing tests from //tests:version_test_binary_3_10
-----------------------------------------------------------------------------
C:/b/yumnn2dr/execroot/_main/bazel-out/x64_windows-fastbuild/bin/tests/version_test_binary_3_10: line 23: tests/version_3_10.exe: Permission denied
```

This seems to be an environment specific or Bazel 8 specific issue.

Running it on my windows laptop, it works.

PR #3406 reproduces the issue.

Oddity: I thought we had bazel 8 + windows testing, so why is it failing now?

The only thing interesting about these tests is they're a shell test that runs the python program. For windows, this means it runs an exe that executes a zip file.

Theory: Possibly related to symlinks? If the test copies the files locally, then the binary-under-test runs successfully.
