Migrate upload-artifact GitHub Action to v4 from v3

[EdmondChuiHW]

Summary

CI in this repo has been failing since Jan 30, 2025.

This PR makes the migration as detailed: https://github.com/actions/upload-artifact/blob/main/docs/MIGRATION.md

Test plan

Tests now run. They're failing, but they run. To be investigated in follow-ups

• This change maintains backwards compatibility with previous Local Storage data (if modifying settings, experiments, or other persisted client state).

Upstreaming plan

• This commit should be sent as a patch to the upstream devtools-frontend repo. I've reviewed the contribution guide.
• This commit is React Native-specific and cannot be upstreamed.
