Post setup Python step fails (pipenv cache)

Description: A clear and concise description of what the bug is.

Hey! So this used to work just a few days ago. We’ve been having some issues with cache in the last few days (see here for details), this is a brand new issue which I think might or might not be related to the previous problem. Simply put, the action fails in the post step with the following message.

Post job cleanup.

Error: Cache folder path is retrieved for pipenv but doesn't exist on disk: /home/runner/.local/share/virtualenvs

Here’s the actual step:

Run actions/setup-python@v3.1.2

Hi @dmitry-shibanov no updates beyond that this is still an issue. I tried removing the cache key which obviously removes the error but after adding it back, the error came back too. So I am stuck it seems between not having caching or receiving this error. I don’t have this confirmed yet, but I suspect this error happens only on the master branch and not in other branches. Also this is interesting to me, after I added back the cache key, the next run produced this:

Run actions/setup-python@v3.1.2
  with:
    cache: pipenv
    python-version: 3.9.13
    token: ***
Successfully setup CPython (3.9.13)
pipenv cache is not found

And then in post step

Post job cleanup.
Error: Cache folder path is retrieved for pipenv but doesn't exist on disk: /home/runner/.local/share/virtualenvs

It would appear the pipenv cache implementation assumes it will be at this location, making PIPENV_VENV_IN_PROJECT probably unworkable at present versions of setup-python actions: https://github.com/actions/setup-python/blob/main/src/cache-distributions/pipenv-cache.ts#L25
