Update GitHub Actions to Node.js 24-compatible versions (#3828)

GitHub is deprecating Node.js 20 for GitHub Actions. Actions will be
forced to run on Node.js 24 starting June 2, 2026, and Node.js 20 will
be removed from runners on September 16, 2026. Example
[warning](https://github.com/pytorch/tutorials/actions/runs/24339682714/job/71109101345?pr=3826):
```
Node.js 20 actions are deprecated. The following actions are running on Node.js 20 and may not work as expected: actions/checkout@v3, nick-fields/retry@3e91a01, pytorch/test-infra/.github/actions/setup-ssh@main. Actions will be forced to run with Node.js 24 by default starting June 2nd, 2026. Node.js 20 will be removed from the runner on September 16th, 2026. Please check if updated versions of these actions are available that support Node.js 24. To opt into Node.js 24 now, set the FORCE_JAVASCRIPT_ACTIONS_TO_NODE24=true environment variable on the runner or in your workflow file. Once Node.js 24 becomes the default, you can temporarily opt out by setting ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true. For more information see: https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/
```

This PR updates all actions in this repo to versions that support
Node.js 22+:

- actions/checkout: v2/v3/v4 → v6
- actions/setup-python: v2/v4 → v5
- actions/github-script: v6 → v7
