ci(governance): bump governance-reusable.yml pin to include hypatia#566 baseline fix

This repo's pin predates hyperpolymath/standards PRs #455/#464/#466,
which fixed the Validate Hypatia Baseline job to actually consult
.hypatia-baseline.json's content instead of failing on any raw
finding count. Without this bump, this repo keeps re-failing on
already-reviewed/accepted findings indefinitely.
