This PR fixes the solution for a missing Mix manifest.

The exception message changed slightly a few months ago laravel/framework#42082

I'm also wondering if there's a reason why this solution suggests npm ci over npm install? I'm assuming it's because people run into this more often in CI/prod than local development where that might be the preferred command?

Yes, indeed. In hindsight, it might be better to suggest npm instal, I'll take care of that
