Fix: Add newline to fix SyntaxError in example code

## Description

The original example code triggers a SyntaxError due to a missing line break between two statements:
```python
from pprint import pprint pprint(fill_mask(f"तिमीलाई कस्तो {tokenizer.mask_token}."))
```


## Changes

Replaced:
```python
from pprint import pprint pprint(fill_mask(...))
```
with:
```python
from pprint import pprint
pprint(fill_mask(...))
```

## Testing
The code has been successfully tested and runs without error.

## Note
This contribution is part of an ongoing research initiative to systematically identify and correct faulty example code in Hugging Face Model Cards.
We would appreciate a timely review and integration of this patch to support code reliability and enhance reproducibility for downstream users.
