Add Sentry SvelteKit SDK via `sv` CLI

### Problem Statement

Nowadays, the `sv` CLI is the official Svelte project scaffolding and support CLI. I talked to one of the maintainers at Svelte Summit and we briefly discussed adding an option to add the Sentry SDK to a project via `sv`. This would be cool, because it's the svelte-native way of adding important plugins and tools to SvelteKit projects.

### Solution Brainstorm

- discuss if this can actually get merged
- invoke the Sentry wizard from within the `sv` flow -- this should be doable according to maintainers
