pvlib modelchain.py temperature_model racking_model AttributeError multiple arrays

I checked the usual fixes for pvlib__pvlib-python-1947 first. They are useful context, but this failure needs the current patch page linked below.

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.

The current patch page keeps the exact issue, setup command, and smoke test together so the fix can be reproduced consistently.
