Add support for macOS

[elliott-miller]

PowerShellExecutor.instance creates an UnsupportedOsPowerShellExecutor on MacOS. The LinuxPowerShellExecutor works fine on macOS assuming Powershell is installed. See the following hack:

  public static void main(String[] args)
      throws ClassNotFoundException, NoSuchMethodException, InvocationTargetException, InstantiationException, IllegalAccessException {
    var c = Class.forName("com.github.frimtec.libraries.jpse.LinuxPowerShellExecutor");
    var constructor = c.getDeclaredConstructor(Path.class);
    constructor.setAccessible(true);

    var executor = (PowerShellExecutor) constructor.newInstance((Path) null);

    System.out.println("PowerShell runtime version " +
        executor.version()
            .orElseThrow(() -> new RuntimeException("No PowerShell runtime available")));

    System.out.println(executor.execute("Write-Host Hello PowerShell!").getStandardOutput());
  }

Outputs

PowerShell runtime version 7.3
Hello PowerShell!

Hi @elliott-miller
Can you do me a favour and let me know what System.getProperty("os.name") returns on MacOS.
I have no MacOS at hand ;-)
I will then prepare a fix.

[frimtec]

Should be fixed with release 1.3.3.
Would be great to get your feedback @elliott-miller, as I can't test it.

In answer to your earlier question....

System.out.println(System.getProperty("os.name"));

Prints

Mac OS X

I have tried 1.3.3 and can confirm it works, many thanks!
