Fix hardcoded Node version and restore yalc command consistency

Critical fixes:
1. Use translated node-version from matrix instead of hardcoded '20'
   - Latest config will now correctly use Node 22 instead of Node 20
2. Restore yalc command to match other workflows: 'cd packages/react-on-rails && yalc publish'
3. Re-enable conditional yarn cache (disabled for Node 22 due to V8 bug)

This ensures the matrix actually controls which Node version is used.
