Set modern-installation config option to false

As of Poetry v1.4.1, packages were required to use modern installation (see: python-poetry/poetry#7686). This is potentially problematic when relying on older versions of packages and for packages who are still using non-modern installers. This commit adds an additional step to disable that modern-installation requirement, which should get the workflow working again.
