pexpect: PopenSpawn() env arg hint could be improved

1

[Currently](https://github.com/python/typeshed/blob/main/stubs/pexpect/pexpect/popen_spawn.pyi#L20) the hint says that `env` is `os._Environ[str] | None`, but in practice it's not as specific. It's passed unmodified to `subprocess.Popen`, so maybe it should simply be `subprocess._ENV` if...

Running tests shouldn't print warnings, especially so many.
