Fix: AttributeError when using .iloc with pyarrow-backed Series in Pandas #61311
fix : #61311
### Solution:
The problem arises when the code tries to access `.max()` and `.min()` on `ArrowExtensionArray`. To fix this, we can replace `.max()` and `.min()` with `np.max()` and `np.min()`, which can handle these arrays correctly.

Here is the modification to be made:

```python
# check that the key does not exceed the maximum size of the index
if np.max(arr) >= len_axis or np.min(arr) < -len_axis:
    raise IndexError("positional indexers are out-of-bounds")
```
