fix(draggable): move target instead of handle

[jemand771]

since the handle element is a child of the target element, it still gets moved as expected. this was probably more of a typo than an actual bug.

fixes #84

I have no idea how to automatically test this. Since the draggable directive didn't have tests before and this bug was more of a typo than a logic issue, imo it's fine without tests (for now)

But what caused the issue? It worked in the past.

see this line in https://github.com/ngneat/dialog/commit/f5575f59da2fb61b9c0aa229e8890eaf32a2a56c

in some other places in that file, the (correct) change

- this.renderer.setStyle(this.handle, 'cursor', '');
+ this.handle.style.setProperty('cursor', '');

was made. but for the transform line, this happened:

-           this.renderer.setStyle(this.target, 'transform', transform);
+           this.handle.style.setProperty('transform', transform);

-> accidentally applying the transform to the handle instead of the target.
