Still using the outdated actions will generate several warnings in CI runs, for example in https://github.com/simdjson/simdjson/actions/runs/5279348647:

Node.js 12 actions are deprecated. Please update the following actions to use Node.js 16: actions/checkout@v2, actions/cache@v2. For more information see: https://github.blog/changelog/2022-09-22-github-actions-all-actions-will-begin-running-on-node16-instead-of-node12/.

The PR will get rid of those warnings.
