Windows: `pywin32` doesn't work with the hermetic Python toolchain

# 🐞 bug report

### Affected Rule

rules_python

### Is this a regression?

Probably not.

### Description

I'm trying to do `import win32api` on Windows, but got
```
ModuleNotFoundError: No module named 'win32api'
```
even if I specify `pywin32==303` in the requirements.txt file.

## 🔬 Minimal Reproduction

Fetch the reproducible case at https://github.com/meteorcloudy/my_tests/tree/master/pywin32_test

then run
```
bazel run //:bin
```

Comienza con la reproducción enlazada de pywin32_test, su requirements.txt y el punto de entrada bazel run //:bin; inspecciona cómo la toolchain hermética de rules_python gestiona pywin32 en Windows. Reproduce el import faltante de win32api y el error de carga de DLL, y verifica después que el ejemplo se ejecuta correctamente con pywin32==303.
