CI dependencies installation error

[AggelosMargkas]

After 5 consequent releases of new versions of pipenv for the month of August, there seems to be something missing from the previous versions. As a result this raises an error on CI when installing the environment dependencies.

The history of releases can be seen here.

One of the missing dependencies is "virtualenv-clone", however the raised error is not based on that specific dependency.

As a workaround

I propose using the last version of pipenv for the month of July (2023.7.23). This way the dependency installation of CI works fine.

I will follow the pipenv releases and test them. If pipenv stops releasing new versions and the a3k CI still has a problem, then I can maybe contact the authors with our error to provide some further information.
