Poetry cache key is not unique for pypy

[bkeryan]

Bug Report

setup-poetry uses platform.python_version() to get the Python version to use in the cache key, but this does not distinguish between CPython and PyPy.

PS C:\dev\python-actions> python
Python 3.11.11 (0253c85bf5f8, Feb 26 2025, 10:43:25)
[PyPy 7.3.19 with MSC v.1941 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>> import platform
>>>> platform.python_version()
'3.11.11'

Repro or Code Sample

ni/hightime#63 uses setup-poetry with pypy3.10 and pypy3.11.

Expected Behavior

The cache key is unique across Python versions.

Current Behavior

pypy3.10: key: hightime-Windows-pypypy7.3.19-c948617eededdca0b593f6f801a4f2af99b2349bf4dd5f2b6d76d20c3cfe67b9
pypy3.11: key: hightime-Windows-pypypy7.3.19-c948617eededdca0b593f6f801a4f2af99b2349bf4dd5f2b6d76d20c3cfe67b9

Possible Solution

Use sys.implementation.name and/or sys.implementation.version

Context

Updating hightime to use ni/python-actions

Your Environment

• ni/python-actions version: v0.3.0
• Python version: pypy3.10, pypy3.11

AB#3163510

setup-python's python-version output has the same problem: actions/setup-python#1109
