It is useful to have a deployment preview for each pull request.

Additional context

Hal will give permissions to the CfJ Vercel and Supabase account. Let me know if you need it.

I'm using this guide to connect to the hackdays project in the production environment for both Production and Preview.
https://supabase.com/docs/guides/integrations/vercel

There is no way to connect to multiple projects in this guide, so if I need to change the Supabase project in Preview, I'm going to do it a little differently, but I'd love to hear your thoughts on how to do it!

Is it possible to deploy nextjs instance to Vercel with GitHub Actions for the preview site?
