CI: bump GitHub Actions to Node.js 24 versions

Silence the deprecation warnings reported on
https://github.com/syoyo/tinygltf/actions/runs/25610558215 by upgrading
all `actions/checkout` usages from v1/v2/v3/v4 to v5 (Node 24 runtime)
and the CodeQL actions from v2 to v3.

msys2/setup-msys2 stays at v2 — it's the latest tag.
