ndarray.round() stopped working without an argument.
### Description

Numpy `round()` as a ndarray member function used to work without an argument but it is no longer working.

```python
_ = jnp.zeros(1).round()
```

Expected to execute without an error, but fails with error message

```
TypeError: round() missing required argument 'number' (pos 1)
```

According to Numpy documentation, this should work without an argument.
