File setup.py of Package failed_python-ly

If the package does not include tests, we need to ensure the `setup.py` file specifies the test suite. Add the following lines to include a basic test suite:

```python
from setuptools import setup, find_packages

setup(
    name="python-ly",
    version="0.9.8",
    packages=find_packages(),
    # Add test suite configuration
    test_suite="tests",
    # Other metadata remains unchanged
)
```
