Bug with vertical GroupNode

[AakashTiwari1027]

When trying to create a GroupNode with NodeGraph.set_layout_direction(1) it throws the following error:

Traceback (most recent call last):
File "C:\Users\awant\AppData\Local\Programs\Python\Python311\Lib\site-packages\NodeGraphQt\qgraphics\node_base.py", line 197, in paint
self._paint_vertical(painter, option, widget)
File "C:\Users\awant\AppData\Local\Programs\Python\Python311\Lib\site-packages\NodeGraphQt\qgraphics\node_group.py", line 125, in _paint_vertical
painter.setBrush(QtGui.QColor(*self.color).dark(180))
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'QColor' object has no attribute 'dark'. Did you mean: 'darker'?

Side Note: Would be greatly appreciated if the name of vertical nodes appeared on the node instead of to the right :)

It might be a no good idea putting the name on the node because there is no an appropriate place.
