Includes the move from the `svelte-preprocess` package for preprocessing
to `@sveltejs/vite-plugin-svelte` which allows us to use Vite also for
preprocessing.
Also had to remove the `vite-plugin-rewrite-all` again since they don't
support vite@4. So I wrote the plugin myself and without the dependecies
used by `vite-plugin-rewrite-all`.
