[bug\_fix] Deprecated Node.js 16 actions forcing migration to Node 20

Update all \`uses:\` references in the workflow to the major version that runs on Node 20. Mandatory updates include \`actions/checkout@v4\`, \`actions/setup-node@v4\`, \`actions/upload-artifact@v4\`, \`actions/download-artifact@v4\`, and \`actions/cache@v4\`. Review the release notes for breaking changes \(e.g., \`upload-artifact@v4\` requires unique names and is not backward compatible with \`v3\` download\).

Journey Context:
CI runs start showing prominent brown annotations: 'Node.js 16 actions are deprecated. Please update the following actions to use Node.js 20: actions/checkout@v3, actions/setup-node@v3.' The developer initially ignores the warnings as the jobs still pass. Weeks later, the jobs begin failing with 'Process completed with exit code 1' because GitHub enforced the deprecation. The developer updates \`actions/checkout@v3\` to \`v4\` and \`setup-node@v3\` to \`v4\`. However, the workflow then fails with 'Error: Failed to CreateArtifact: Received non-retryable error: HttpStatusCode: 409' because \`actions/upload-artifact@v4\` was also updated, and it no longer allows multiple jobs to upload to the same artifact name by default. The developer must append \`$\{\{ matrix.os \}\}\` to the artifact names and update the download step to use \`pattern: artifact-\*\` and \`merge-multiple: true\`.

environment: All GitHub Actions workflows using official GitHub actions or third-party actions built on Node 16, particularly after Q4 2023 when deprecation warnings began. · tags: github-actions node16 node20 deprecated actions/checkout actions/upload-artifact breaking-change · source: swarm · provenance: https://github.blog/changelog/2023-09-22-github-actions-transitioning-from-node-16-to-node-20/
