Fix check-typescript script to use workspace type-check scripts

The check-typescript script was using invalid nps syntax:
  nps "build --noEmit"

This doesn't work because:
1. There's no 'build' script in package-scripts.yml (only build.prepack)
2. nps doesn't support passing arguments to scripts this way

Fixed by running the type-check script from each workspace package:
- yarn workspace react-on-rails run type-check
- yarn workspace react-on-rails-pro run type-check
- yarn workspace react-on-rails-pro-node-renderer run type-check

All three workspace packages already have type-check scripts that run
tsc with --noEmit and --noErrorTruncation flags.

Tested locally and passes successfully.
