Vercel Python - vercel build looks for and can't find /supabase/migrations/...

[jtewright]

Describe the bug
Python project deployed to Vercel. Using Supabase CLI for local dev, db migrations etc. When building on Vercel, the vercel build process tries to open /supabase/migrations/*.sql but can't find those files. Not sure why vercel is trying to open those files, perhaps it opens all files; not sure why it can't find them.

To Reproduce

1. Create python project, deploy to vercel
2. install supabase cli locally, link to db, db pull migrations
3. push the updated project to github, deploy to vercel

Expected behavior
Vercel finds the supabase/migrations/*.sql files and does nothing with them, or ignores them
