Fix doctests by reordering coordinates in expected outputs

[Copilot]

This PR fixes doctest failures in the repository by correcting the coordinate ordering in expected outputs to match the actual xarray behavior.

Issue Identified

Two doctest failures were found:

1. xskillscore.core.probabilistic.discrimination - coordinate ordering mismatch
2. xskillscore.core.stattests.multipletests - coordinate ordering mismatch

The issue was caused by xarray's coordinate ordering in outputs, which differs from what was documented in the expected test outputs.

Changes Made

• discrimination function: Reordered coordinates in expected output from forecast_probability, event to event, forecast_probability
• multipletests function: Reordered coordinates in expected output from x, y, result to result, x, y

Verification

• ✅ All 32 doctests now pass successfully
• ✅ No functional code changes - only documentation/test output corrections
• ✅ Changes are minimal and surgical, affecting only the expected output formatting in docstrings

This fix addresses issue #435.

Original prompt

The task is to fix the doctests in the repository by reordering the test cases so that they run correctly. This includes identifying the current issue with the doctests, rearranging the test cases to ensure they execute in the proper order without errors, and verifying the fix by running the doctests. The fix should be implemented in the branch associated with issue #435.

Fixed the doctest failures. The issue was that coordinate ordering in xarray outputs had changed. I reordered the coordinates in the expected outputs for two functions:

1. discrimination - swapped order of event and forecast_probability coordinates
2. multipletests - moved result coordinate before x and y coordinates

All 32 doctests now pass. Commit: d9ec2d4

Nice. But did manually quicker.
