Build warning regarding deprecated options

[stefan6419846]

When building the package (in this case, version 1.8.7), using python3 -m build ., I get some warnings:

/tmp/build-env-yi1s6la0/lib64/python3.9/site-packages/setuptools/config/setupcfg.py:293: _DeprecatedConfig: Deprecated config in `setup.cfg`
!!

        ********************************************************************************
        The license_file parameter is deprecated, use license_files instead.

        This deprecation is overdue, please update your project and remove deprecated
        calls to avoid build errors in the future.

        See https://setuptools.pypa.io/en/latest/userguide/declarative_config.html for details.

The [wheel] section is deprecated. Use [bdist_wheel] instead.
