Due to https://github.com/uiri/toml/issues/270, vulture won't run for projects with a `pyproject.toml` that contain an array with mixed types. According to https://github.com/python-poetry/poetry/issues/7094#issuecomment-1328127456, this is not an issue in the `tomllib` in Python 3.11+ or its backport (https://github.com/hukkin/tomli). It looks like this should be a quick swap. I'll send a PR along when I have a moment.
