fix(ci): use the canonical Scorecard wrapper instead of a local copy

The staleness gate rejects ANY workflow containing both
`ossf/scorecard-action@` and `github/codeql-action/upload-sarif@`, whatever
its triggers. 273 of 302 estate repos already call standards'
`scorecard-reusable.yml`, which reports with `results_format: json` +
`publish_results: true` and never uploads SARIF to Code Scanning.
