CI Mark scikit-learn example as xfail due to upstream bug

[betatim]

The scikit-learn example sometimes fails (about 80% of the time) with Python 3.14.7. That version of Python introduced a stricter check which catches what I think is a bug in the callback infrastructure of scikit-learn.

[csadorf]

Please consider limiting to sklearn 1.9.0 if that makes sense.

[betatim]

Hopefully this will be fixed by the next release so we only need to match exactly 1.9.0
