DOC: sparse: `sparse.eye_array` does not accept `tuple[int, int]` as the docs say that it should
### Describe your issue.

`scipy.sparse.eye_array` does not accept `m: tuple[int, int]` as the docs suggest is should:

https://github.com/scipy/scipy/blob/964f0bb6701dc17b51b842382ced0fa2ee318377/scipy/sparse/_construct.py#L350-L353

This is the case with at least `1.14.1` and `1.15.0rc1`

### Reproducing Code Example

```python
from scipy.sparse import eye_array
eye_array((1, 1))
```


### Error message
