• #14292 21d048f Thanks @dependabot! - Fix SvelteKit project creation failing with "Error parsing file: svelte.config.js"

  As of sv 0.16, newly scaffolded SvelteKit projects no longer include a svelte.config.js file, and the adapter is configured in the Vite config instead. C3 now updates the adapter import in vite.config.ts/vite.config.js rather than svelte.config.js, so creating a SvelteKit project succeeds again.
