Latest 3.8 image causing failures

[henrickgoldwurm]

The latest cimg/python:3.8 image is causing failures during dependency installations. I tested with an empty commit on a passing branch to confirm it wasn't an issue in my code changes. Switching to cimg/python:3.8.7 seems to fix the issue.

Looks like it may be related to the move to 3.8.8 in #77

@henrickgoldwurm - correct, using the image cimg/python:3.8 is only tied to the major and minor versions; any patch release in cadence with the python releases will be published and that tag overridden. If you need a specific version of python, you should specify the subminor version, e.g cimg/python:3.8.7.

If you intended to keep with the release cadence, it's also possible that cached dependencies from the older versions of python via pyenv are being used, see some details here: CircleCI-Public/python-orb#51

Yup, resetting the cached dependencies fixed the issue. Thank for the quick reply!
