On GitHub hosted runner: Unable to locate executable file: poetry

[mbrancato]

Description:
Poetry appears to be required prior to running actions/setup-python with cache: 'poetry' set. This is on a GitHub hosted runner. I'm sure to fix this poetry needs to be installed before running this action. That said, I generally prefer to do that after installing Python. Also, actions/cache against .venv works fine without poetry being installed.

Given the "advanced usage" shows installing poetry first, maybe listing that as a dependency is the fix here, however, I don't think poetry is actually needed unless the virtual env is going into a different location.

	**Caching poetry dependencies:**
	```yaml
	steps:
	- uses: actions/checkout@v4
	- name: Install poetry
	run: pipx install poetry
	- uses: actions/setup-python@v4
	with:
	python-version: '3.9'
	cache: 'poetry'
	- run: poetry install
	- run: poetry run pytest
	```

full error:

Unable to locate executable file: poetry. Please verify either the file path exists or the file can be found within a directory specified by the PATH environment variable. Also check the file mode to verify the file is executable.

Action version:
v4

Hello @mbrancato. It is an expected behaviour because the action uses poetry to get configuration. For now I'm going to close the issue.
