fix gh artifacts upload with the latest action version

[moukoublen]

Summary of your changes

It seems that after a version update of upload-artifact something is wrong when we give a folder as a path to upload.

In our CI, we upload the produced Docker images as artifacts, which are later downloaded and used for kspm testing.

I didn't investigate the action code to find out why, but as a workaround, I changed the upload path from folder to wildcard pattern, and it works.

        path: |
          ${{ inputs.docker-images-folder }}/*.tar
