Linter complains about pyproject.toml

My (version of) tombi-lint complains about the [tool.pyright] section in [pyproject.toml](https://github.com/nens/cookiecutter-python-template/blob/master/%7B%7B%20cookiecutter.project_name%20%7D%7D/pyproject.toml#L33): `include = "src"` should be an array. Pyright [documentation](https://github.com/microsoft/pyright/blob/main/docs/configuration.md#environment-options) says so too.
