Version not found when using new arm-based linux runners (ubuntu 22.04)

[juanitosvq]

Description:
I just created a runner using the newly available arm-based linux images for GitHub actions: https://github.blog/changelog/2024-06-03-actions-arm-based-linux-and-windows-runners-are-now-in-public-beta/
I am using Ubuntu 22.04 for this runner:

When trying to use the actions/setup-python@v5 to set up python 3.9, the action is failing with:

The version '3.9' with architecture 'arm64' was not found for Ubuntu 22.04.
The list of all available versions can be found here: https://github.com/raw/actions/python-versions/main/versions-manifest.json

Action version:
actions/setup-python@v5

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Tools version:
Python 3.9

Repro steps:
Create a runner using the new arm-based linux, selecting Ubuntu 22.04 by Arm Limited as Image name. Use that new runner in a GitHub Action and try to set up python3.9 using the action.

Expected behavior:
Should be able to set up python 3.9 in an arm-based Ubuntu 22.04 runner.

Actual behavior:
Unable to set up python 3.9 in an arm-based Ubuntu 22.04 runner.

It's a little surprising setup-python doesn't support ARM-based Python versions yet, given ARM-based runners are in public beta now. We were able to get around this by running jobs in a container (not using setup-python).
