`resolve.tsconfigPaths` fallback conflicts with the generated tsconfig

### Describe the problem https://github.com/sveltejs/kit/issues/16468#issuecomment-5041376925 ### Describe the proposed solution Skip the warning when the user has opted into `resolve.tsconfigPaths`. Detection is the awkward part, `svelte-kit sync` doesn't see the Vite config, so this may need to be part of #16458's restructuring instead. ### Alternatives considered _No response_ ### Importance nice to have ### Additional Information _No response_
