Wrong recovery commands

For anyone reading this. you're better learning to use migrations and db pull push from supabase cli.
`supabase db execute` doesn't work. There's no mention in the supabase docs of it. I am running them with psql instead.

```
psql "<SUPABASE_DB_URL>" -f roles.sql
psql "<SUPABASE_DB_URL>" -f schema.sql
psql "<SUPABASE_DB_URL>" -f data.sql
```
