`optimizeDeps.rollupOptions` will be removed

[sapphi-red]

Describe the problem

optimizeDeps.rollupOptions is used here. I added a runtime deprecation in the latest version of rolldown-vite and I'm planning to remove this in the next version of rolldown-vite.

vite-plugin-svelte/packages/vite-plugin-svelte/src/plugins/setup-optimizer.js

Line 46 in 7527524

optimizeDeps.rollupOptions = {

(Note: build.rollupOptions is also deprecated but would still be there)

Describe the proposed solution

Replace it with optimizeDeps.rolldownOptions.
