LICENSE.txt no longer being packaged in PyPI source

[xylar]

As of the 1.0.0 release (https://pypi.org/project/airflow-provider-great-expectations/#files), it looks like LICENSE.txt is missing from the source tar file on PyPI. It would be good to include it again in the next release.

$ tar xvf airflow_provider_great_expectations-1.0.0.tar.gz
$ cd airflow_provider_great_expectations-1.0.0/
$ ls
great_expectations_provider  PKG-INFO  pyproject.toml  README.md
