Remove legacy Paper renderer shim cleanup from artifact commit workflow (facebook#36297) (facebook#56483)

Summary:
Pull Request resolved: facebook#56483

## Summary

PR facebook#36285 deleted the Paper (legacy) renderer, including the shim file
`scripts/rollup/shims/react-native/ReactNative.js`. However, the
`runtime_commit_artifacts` workflow still tries to `rm` this file after
moving build artifacts into `compiled-rn/`. Since the file no longer
exists in the build output, `rm` (without `-f`) fails and kills the
entire step.

This has caused **every run of the Commit Artifacts workflow to fail
since facebook#36285 landed on April 16**, blocking both `builds/facebook-www`
and `builds/facebook-fbsource` branches from receiving new build
artifacts. This in turn blocks DiffTrain from syncing React changes into
Meta's internal monorepo.
