Update score_new_plugins.yml to use actions/upload-artifact@v4

Current workflow uses v2. This has been causing an automatic failure in scoring jobs.

v3 is being deprecated in 2 months.

Based on `Breaking Changes` as seen on the actions readme, this should work with a simple replacement of the version number.
