ci: re-pin Hypatia scan reusable to standards-main GITHUB_TOKEN fix

Bump the reusable pin from d135b05 (pre-fix) to
e2ef79eecdd623ff631fcbf3fe0268ba4f4ce166, the squash-merge of
standards#429 on main that passes GITHUB_TOKEN to the scanner and
carries --exit-zero + if: always() artifact upload. d135b05 predates
the alert-token fix and abd93c3 (the #429 head) is not an ancestor of
standards/main, so both tripped the Workflow-Staleness governance check.
