NumPy v1.25.0 removes the previosuly deprecated behavior of returning False when an array could not be broadcast. It now raises a ValueError, same as Pandas. numpy/numpy#22707
The Pandas documentation previously highlighted this discrepancy. However, since it now throws an error, it is causing building the documentation to fail.

I removed the mention of NumPy in this section since the behavior is mostly the same (NumPy still treats an array of one item as a scalar, while Pandas doesn't). Would it be preferable to mention that they act the same now?
