Updated the dependency in convex-auth-example

[night niche]

Hi guys!! I’ve been exploring Convex for the past two days and convex made an example project chat application to showcase auth. However, when I tried to run it locally, I encountered an issue because the npm-run-all command dependency was missing. so I fixed it and made PR.
https://github.com/get-convex/convex-auth-example/tree/main

Unfortunately, I received a message indicating that all checks have failed, and it shows:

All checks have failed
1 failing check
@vercel
Vercel — Authorization required to deploy.

This is my first PR, what is the problem?

Ah thanks -- I think we have it set up so only Convex employees can generate preview deployments. I'll make sure your change gets added (this repo is also a little weird because it's actually synced over from https://github.com/get-convex/convex-auth)
