(fix) fix pyproject.toml (#226)

## Summary
In https://github.com/linkedin/Liger-Kernel/pull/218, I fixed the
`tool.setuptools.packages.find` field and tested it only in editable
mode with `pip install -e .`. However, in production mode with `pip
install .`, only the env_report.py file is copied to the Python
site-packages directory. To fix this, adding "liger_kernel.*" to the
include list will ensure that setuptools correctly includes all
subpackages within liger_kernel.
