fix(ci): invoke fhir-gen via direct node path

pnpm bin symlinks aren't reliable in CI (install runs before cli/dist
exists), and npx --package kept resolving to 'fhir-gen: not found'.
The Build workspace packages step ahead of this guarantees the dist
file exists, so calling node on it directly is the most predictable
path.
