Support for configuration variables in workflows (vars)

[ghost]

It seems that the newly implemented vars need to be supported.
https://github.blog/changelog/2023-01-10-github-actions-support-for-configuration-variables-in-workflows/

For example:

on:
  push:
jobs:
  display-variables:
    runs-on: ${{ vars.RUNNER }}
    steps:
    - name: Use variables
      run: |
        echo "Repository variable : ${{ vars.REPOSITORY_VAR }}"
        echo "Organization variable : ${{ vars.ORGANIZATION_VAR }}"

Yes, this should be supported. I'm considering to add minimal support for this at least not to cause errors on vars context.
