fix: Prompt database starter kits

[mathiasgrimm]

It would only prompt for the database when not using a starter kit.

When using a starter kit, it would always use SQLite. Changed to prompt for the database when Interactive.

• No starter kit: https://github.com/laravel/laravel/blob/12.x/composer.json#L46
• Vue: https://github.com/laravel/vue-starter-kit/blob/main/composer.json#L50
• React: https://github.com/laravel/react-starter-kit/blob/main/composer.json#L50
• Livewire: https://github.com/laravel/livewire-starter-kit/blob/main/composer.json#L50

Let me think on this one. I kinda like that you don't have to make too many decisions and everything "just works".
