Update Supabase version and improve Keystatic's configurations

This commit updates the version of Supabase in multiple packages. It also introduces specificity to environment variables in Keystatic configuration and adds a method to create a 'KeyStatic' reader based on the storage kind. Furthermore, minor adjustments have been made to keep the environment variable names consistent.
