docs: align tool inventory with what actually runs (no Grype, no ZAP/nuclei)

CVE matching is done directly against OSV.dev (by purl) and NVD (CVSS, CODESYS
CPE) in pipeline/cve.rs; Grype is not installed or invoked. DAST/pentest use the
in-house compliance-dast agents, not ZAP or nuclei. Found while reconciling the
Certifai requirements spec (Collectives) with the code.
