fix(ci): repin release-please reusable workflow to reachable SHA

The reusable workflow was pinned to f288e5e, a pre-squash-merge
branch-tip commit in Coding-Autopilot-System/.github that became
unreachable when .github PR #16 squash-merged and the source branch
was deleted. Every push-triggered release-please run has since failed
with 'workflow was not found'.

Repin to 64c1673, which is the merged commit on .github's main
branch containing .github/workflows/release-please-reusable.yml.
