Poetry installation fails on PyPy jobs

[Diapolo10]

I'm no entirely sure what happened, but it seems that about two weeks ago, Gr1N/setup-poetry@v8 stopped working with PyPy installations. It took me a while to notice because apparently I'd gotten it mixed up with another problem and didn't take a closer look until now.

As evidence, here's the GHA unit test runs of one of my projects; you can see that since 11th of October, it's given errors since: https://github.com/Diapolo10/iplib3/actions/workflows/unit_tests.yml

Here's the output from a debug mode run:

# Welcome to Poetry!

This will download and install the latest version of Poetry,
a dependency and package manager for Python.

It will add the `poetry` command to Poetry's bin directory, located at:

/home/runner/.local/bin

You can uninstall at any time by executing this script with the --uninstall option,
and these changes will be reverted.

I haven't been able to replicate this issue locally, and I can't tell what could've changed to result to this. I suppose not many people are using this with PyPy considering nobody else has mentioned similar issues lately.

Could someone else verify if the same happens to them?
