💡 Feature request

Feature Name

I was trying to use these actions with a Magento Cloud project. Unfortunately, we don't compute get-magento-version that key for stores.

The Desired Behavior

I would like to be able to drop an action like the following into my Github actions and retrieve the correct Magento version.

steps:
- uses: mage-os/github-actions/get-magento-version@main
  id: get-magento-version
      with:
          working-directory: ${{ secrets.GITHUB_WORKSPACE }}

Your Use Case

As a developer, I would like to be able to compute the currently installed Magento version for Magento Cloud projects from composer.json or composer.lock.
