fix: restore CI and refresh the action bundle

GitHub Actions was failing at tsc --noEmit because TypeScript was not
loading the Node ambient types, so node:* imports and NodeJS
references were reported as missing.

Regenerating dist/index.js on top of origin/master also updates the
checked-in action bundle for the @actions/tool-cache v4 dependency
bump so the shipped action matches the rebased source tree.
