Sebastian Szewczyk a54ba456e7 ci: bump actions/setup-node from v3.9.1 to v6.4.0 (#9589) ...

## Summary
- Bumps `actions/setup-node` in
`.github/actions/prepare_environment/action.yml` from v3.9.1 (Nov 2023)
to v6.4.0 (Apr 2026).
- Motivation: the v3 line runs on a Node 16 action runtime, which GitHub
Actions has been deprecating. v4 → Node 20, v5/v6 → Node 24.
- The only input we pass is `node-version: 20.9.0`. None of the inputs
whose semantics changed across majors (`cache`, `always-auth`,
`registry-url`) are used here, so the upgrade is behaviorally inert for
our usage.

## Test plan
- [ ] CI passes on Linux, macOS, and Windows runners that exercise
`prepare_environment`.
- [ ] No new deprecation warnings related to `setup-node` in the action
logs.
