fix: correctly process the Node V1 dict results on V3 node

[bigcat88]

Found by chance by a type checker, looks like a typo in the code.

Right now NodeOutput.from_dict will always raise an exception, as NodeOutput class does not define args argument as possible kwarg.

Tested on such code in the V3 node:

return {"result": [output_text, "something else"]}

This will lead to such exception during execution:

File "/home/shurik/Comfy/ComfyUI-work/comfy_api/latest/_io.py", line 1541, in EXECUTE_NORMALIZED_ASYNC
    to_return = NodeOutput.from_dict(to_return)
                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/home/shurik/Comfy/ComfyUI-work/comfy_api/latest/_io.py", line 1818, in from_dict
    return cls(args=args, ui=ui, expand=expand)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: NodeOutput.__init__() got an unexpected keyword argument 'args'
