'project.license-files' is defined already. Remove 'tool.setuptools.license-files'

Bug description

I started randomly running into this issue in CI without any code changes and I'm confused as to why. I run pylint as part of pre-commit and during instantiation of pre-commit, I ran into the problem below. If this is better served in the pre-commit repo, please let me know.

Sure enough, going into the temporary repo in /home/jerome/.cache/pre-commit/repoyqo4j89l and modifying the pyproject.toml to remove that license line seems to fix it. I guess I'm also trying to sort out why it randomly broke in CI. We use python 3.11.3 and pip 23.3.2.
