ci(codex): bump public-workflows pin to v2.4.0

[nsportsman]

Bumps the Codex PR reviewer pin to v2.4.0 (f7fb4810).

Why: this repo was pinned to a pre-fix public-workflows version (v2.1.0 / v2.3.1) where Harden-Runner's disable-sudo-and-containers pre-disables sudo on the codex job. openai/codex-action needs sudo to lock its proxy file before it irreversibly drops sudo, so the action exits 1 before any review runs — the Codex review silently fails on every real code PR. (Green checks on docs/release-only PRs are preflight-skips, which masked this.)

Fixed upstream in praetorian-inc/public-workflows#80, released in v2.4.0 (also carries the gpt-5.5 default + CVE-2025-32955 container-lockdown hardening).
