All checks have failed

The message indicates that you are using the deprecated version actions/upload-artifact (v2), which is no longer supported, causing the error.

To fix this:

1. Update the version of the actions/upload-artifact action to the new supported version. To do this, replace the line in your workflow file (e.g., .github/workflows/your-workflow.yml) from:

- name: Upload artifact
  uses: actions/upload-artifact@v2

to:

- name: Upload artifact
  uses: actions/upload-artifact@v3

2. Check the updated file on GitHub to ensure everything works properly after the update.

After making this change, your workflow should run successfully without errors related to deprecated versions.

Yes, i created an issue for it (#909) and will tackle with it when i have time. If you prefer, you can also take it and work on it. Until that's done, this PR will -sadly- be blocked.

I’ve updated the GitHub Actions workflow to address this. The changes include updating action versions, switching Ruby to 3.2, optimizing step order, improving gem installation, and making the validation step more resilient. You can check the details in the commit. Let me know if anything else is needed!

Please update this branch with latest master, then it's good to go.
