1. Updated the tsconfig.json according to official documentation
   https://v3.nuxtjs.org/bridge/overview
   This is to prevent the need to import "ref", "defineComponent" in every component since its already being handled by Nuxt
   Also added "jsx": "react" to exclude the error "--jsx ....." in PiniaLogo.vue component.

2. Refactored the import code for the pinia store included in index.vue to a single-line import

3. Added custom layout and included it in index.vue to indicate how to include layout in Nuxt Bridge considering this was an issue in the discussion below.
