Fix yalc publish command in Pro integration workflow

Change 'yarn run yalc:publish' to 'yarn && yalc publish' for the
react_on_rails_pro package, since it doesn't have a yalc:publish script
defined (only the workspace packages do).

The workflow now:
1. Runs yarn run yalc:publish at root (publishes workspace packages)
2. Runs yarn && yalc publish in react_on_rails_pro (installs + publishes Pro)

This matches the command structure used in the preinstall script.
