fix: always set bindings/exports in Svelte 5 (#2423)

Those two methods are needed in Svelte 5, but we don't always set them. That was fine until TS 5.5, which infers generics slightly differently and turns `Exports` and `Bindings` to `never` if they don't show up in the input (before they were not)
