Update script to use Supbase CLI

[lyqht]

Based on @supabase Launch Week 5 release notes, we can update the GitHub Action script to run Supabase CLI's gen types command instead of using openapi-typescript directly.

Hi @lyqht I tried hard on : https://github.com/alex-galey/generate-supabase-db-types-github-action/tree/supabase-cli
But can't figure out why I'm always getting this Error: error running container
You can check the issue I opened on the main repo

hello @alex-galey, thanks for helping to work on this one! I think the supabase folks replied you on the issue on the main repo, try out that and let me know if it helps!
