Workflow for building macOS package broken

[bedroge]

For some reason the action is suddenly failing due to:

/Users/runner/work/_temp/0902b464-74fc-42e[5](https://github.com/EESSI/filesystem-layer/actions/runs/3451774489/jobs/5761265174#step:6:6)-a721-b4a369a30dd5.sh: line 1: ansible-playbook: command not found

Even though Ansible has been installed without any issues.

Comparing it to the last run that did succeed, I don't see any significant differences.
Failing workflow:

Operating System
  macOS
  11.7.1
  20G918

Succesful one:

We've (temporarily) disabled the workflow in PR #134, as we're not supporting / actively working on support for macOS at the moment anyway.
