Update GitHub Actions to Node.js 24 compatible versions (#100)

Pin all actions to SHA commits targeting Node 24 runtime to address the upcoming Node.js 20 deprecation (June 2, 2026).

Updated:

- actions/checkout v4.3.1 -> v6.0.2
- actions/github-script v7.0.1 -> v8.0.0
- actions/cache v4.3.0 -> v5.0.5
- actions/upload-artifact v4.6.2 -> v7.0.1
- actions/download-artifact v4.3.0 -> v7.0.0
- docker/setup-buildx-action v3.11.1 -> v4.0.0

Not yet available as Node 24:

- lukka/run-vcpkg

Remaining actions that do not leverage Node.js 20 were not updated.
