deprecation warning from pip

[InjAnnuity1]

Installing questionnaire is successful, but pip 23.0 also produces the following warning:

DEPRECATION: questionnaire is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559

Not sure how to resolve this myself, but I thought you'd want to know.
