`version_option` ignores `package_name`

```python
import click

PACKAGE_NAME = "click-sub-commands"

@click.command()
@click.version_option(package_name=PACKAGE_NAME)
def main():
    print("Hello world")

if __name__ == "__main__":
    main()
```

Expected:
```
click-sub-commands, version 0.1.0
```

Actual:
```
main.py, version 0.1.0
```


Environment:

- Python version: 3.13.7
- Click version: 8.3.0
