pvlib modelchain.py temperature_model racking_model AttributeError multiple arrays

Older notes for pvlib__pvlib-python-1947 can help with context, but they do not fully cover the current failure mode.

Why the common answers are incomplete

ModelChain temperature_model inference can raise AttributeError by reading PVSystem.racking_model on systems with multiple arrays.

Handle multi-array systems by inspecting each array racking_model instead of using the singular PVSystem.racking_model attribute.

The references note that PVSystem.racking_model is not supported for multi-array systems, so the fix should be array-aware.
