doc: input_signature cannot be a numpy array unlike documentation says #2396
Description
Describe the bug
The readme of from_keras (here: https://github.com/onnx/tensorflow-onnx?tab=readme-ov-file#from_keras-tf-20-and-newer)
says: "input_signature: a tf.TensorSpec or a numpy array defining the shape/dtype of the input"
However, this is wrong in two levels:
First, providing a single value gives an error saying that a list or tuple of TensorSpec was expected.
Second, providing a tuple with numpy arrays is also not allowed.
Urgency
