Update GitHub Actions to Node 24 compatible versions (#6007)

Upgrade actions/checkout, setup-node, upload-artifact, download-artifact,
and codeql-action to their latest major versions that run on Node 24.

Replace NathanFirmo/wait-for-other-job with native needs: build for
test-unit and test-integration jobs.

Fixes #6006
