🚀 Feature: Link to create-typescript-app.dev

### Feature Request Checklist

### Overview

I bought the `create-typescript-app.dev` domain. Great! Filing this issue to track updating any docs and the GitHub repo to link to it.

See also #1193 for _making_ a docs website.

### Additional Info

I bought it on namecheap on @atilafassina's recommendation. Which was nice, it was $6 cheaper than the cheapest other common site. But now it doesn't load (`DNS_PROBE_FINISHED_NXDOMAIN`). So this issue is blocked and it's all Atila's fault. 😤
