Description
What is your issue?
numpy 2 has deprecated passing 2D vectors to np.cross. We should do the same presumably, or fix it so that the numpy warning isn't raised..
I deleted the doctests in https://github.com/pydata/xarray/pull/9177 to fix CI.

Research direction
Start by locating xarray's cross implementation and reviewing the doctests removed in pull request 9177. Clarify whether the goal is to mirror NumPy's deprecation or avoid its warning, then verify the chosen behavior with the relevant cross checks and CI.
