Update GitHub Actions to latest versions

[Copilot]

Updates workflow actions to their latest releases for improved security and Node.js 24 support.

Changes

• actions/checkout: v4 → v6

  • Credentials now stored in isolated $RUNNER_TEMP location

• actions/setup-node: v4 → v6

  • Automatic npm caching when packageManager field present

• actions/configure-pages: v4 → v5

  • Enhanced config auto-detection for static site generators

Compatibility

Requires GitHub-hosted runners with:

• Actions Runner ≥ v2.329.0 (checkout)
• Actions Runner ≥ v2.327.1 (setup-node)

All current GitHub-hosted runners meet these requirements.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/repos/actions/checkout/releases/latest
  • Triggering command: /usr/bin/curl curl -s REDACTED (http block)
• https://api.github.com/repos/actions/configure-pages/releases/latest
  • Triggering command: /usr/bin/curl curl -s REDACTED (http block)
• https://api.github.com/repos/actions/deploy-pages/releases/latest
  • Triggering command: /usr/bin/curl curl -s REDACTED (http block)
• https://api.github.com/repos/actions/setup-node/releases/latest
  • Triggering command: /usr/bin/curl curl -s REDACTED (http block)
• https://api.github.com/repos/actions/upload-pages-artifact/releases/latest
  • Triggering command: /usr/bin/curl curl -s REDACTED (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
