macOS package installation fails for non-privileged user

[AttilaT]

Description:
Can not install python with a non-privileged user, even if the user is part of admin group and has sudo permission to use /usr/sbin/installer

The error is:

  Error: ln: python311: Permission denied
  Error: The process '/bin/bash' failed with exit code 1

The error occurs due to the fact that /Library/Frameworks/Python.framework/ is owned by root:admin and the setup.sh is creating simbolic links to bin folder in /Library/Frameworks/Python.framework/<versions>/bin which it doesn't have permissions.

Action version:
Same error on v5, v4, v3

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted on EC2 metal

Tools version:
Tested on python v3.11

Repro steps:
Simply run the installation as a non-privileged user

Expected behavior:
Ideally, the installation is performed directly into the cash folder instead of system wide.

Actual behavior:
Installation fails
