[Feature] Add an option for users to select Pinia or VueX as a default state management

[ThinhVu]

It's better to have a step that users can select:

• Default: Don't include state management
• Pinia: Using Pinia as the default store
• VueX: Using VueX as the default store

I think I'd want to keep the templates closer to Vite-only features + X framework for now. So framework-land libraries like pinia, vue-router, etc, shouldn't be kept here. It's also a bit hard to maintain this matrix with how the templates are setup now.

I believe pinia is the recommended approach moving forward too, and npm create vue covers it.
