feat: import updated <SliceSimulator> on new projects

Description

This PR updates the Slice Simulator page templates generated during project initialization to import the <SliceSimulator> component from its new location in the main SDK packages instead of the adapter's /simulator subpath.

Changes by adapter:

• Next.js (adapter-next):

  • App Router: Imports from @prismicio/next instead of @slicemachine/adapter-next/simulator
  • Pages Router: Imports from @prismicio/next/pages instead of @slicemachine/adapter-next/simulator

• Nuxt (adapter-nuxt):

  • Removed the explicit SliceSimulator import (now auto-imported by the Nuxt module)
  • Reordered Vue SFC to place <script> before <template> (follows Vue style guide recommendation)

• SvelteKit (adapter-sveltekit):

  • Combined SliceSimulator and SliceZone imports from @prismicio/svelte instead of importing SliceSimulator from @slicemachine/adapter-sveltekit/simulator

Checklist

• If my changes require tests, I added them.
• If my changes affect backward compatibility, it has been discussed.
• If my changes require an update to the CONTRIBUTING.md guide, I updated it.

Preview

N/A — This change affects generated code during project initialization, not visual components.

How to QA ¹

1. Create a new project with each adapter (Next.js App Router, Next.js Pages Router, Nuxt, SvelteKit)
2. Verify the generated Slice Simulator page imports SliceSimulator from the correct package:
   • Next.js App Router: @prismicio/next
   • Next.js Pages Router: @prismicio/next/pages
   • Nuxt: No explicit import (auto-imported)
   • SvelteKit: @prismicio/svelte
3. Verify the Slice Simulator page works correctly in each framework
