Unable to get PyPy3 to install

[Cyb3r-Jak3]

Description
Pypy versions appear to be missing from the setup-python action but are but show as cached tools. This is causing jobs using pypy to fail,

Question, Bug, or Feature?:

Virtual environments affected

• macOS 10.15
• Ubuntu 16.04 LTS
• Ubuntu 18.04 LTS
• Ubuntu 20.04 LTS
• Windows Server 2016 R2
• Windows Server 2019

Expected behavior
The virtual environment is able to use pypy and pypy3 to complete python tests

Actual behavior
Get a failure reason:

Version pypy3.6.9 with arch x64 not found
The list of all available versions can be found here: https://raw.githubusercontent.com/actions/python-versions/main/versions-manifest.json

I checked the link and there are no pypy versions there. However, all the READMEs for the virtual-environments have pypy3 listed.

Repro steps
Action that failed: https://github.com/Cyb3r-Jak3/html5validator/actions/runs/283323536. Link the workflow config: https://github.com/Cyb3r-Jak3/html5validator/blob/pypy3_support/.github/workflows/main.yml

Steps to reproduce:

1. Setup up the python action to use either pypy or pypy3
2. Push the changes and the job will fail to run because it can not find the version.

I've been using these for a while, they worked an hour ago: https://github.com/pybind/pybind11/runs/1196848139?check_suite_focus=true

Wrong spelling, perhaps? pypy3.6.9 vs pypy3?

I'd love to see 7.3.2, though. ;)

Unlike normal Python, GHA can't install arbitrary versions of PyPy. It's hard to even write versions of pypy since there's 2 and now 3 (with 3.7 alpha) versions of Python mixed with the PyPy version.

@Cyb3r-Jak3 , yes, @henryiii is absolutely right.
You can't specify exact pypy version as task input. It is by design for now.
See related code: https://github.com/actions/setup-python/blob/main/src/find-python.ts#L176

Yup, I was able to get it to work now. My issue is that when I was starting, I was converting from Travis CI. That format is pypy for pypy2 and pypy3 for pypy3.

Thanks all for your help!
