trash-rs: Tests on MacOS fail because AppleScript is not available on Github Actions

Thanks for reporting! I’d hope that this fixes itself once the runner-image receives updates, but if not it should be possible to use the alternative implementation in tests as well (or force using older runners while available).

In #8 there has been discussion on how to make improvements and apple-script seemed like the easiest way to achieve these, but if MacOS 13 keeps up these errors, this would be prohibitive.

I think we could introduce a Trash object, somwething that could be used like this:

use trash::TrashExtMacOS;

let mut trash = Trash::new();
// This method is from the trait `TrashExtMacOS`
trash.set_use_finder(false);
// The following uses `recycleURLs` and so does every delete operation until `set_use_finder` is called again
trash.delete("my_file");
