Scaffold the website with Svelte

[joaopgrassi]

We'll be using Svelte/SvelteKit to build the website. I have a sample already running from GitHub pages https://github.com/joaopgrassi/sveltekit-ghpages that demonstrates how to read from the JSON files and populate the drop-downs.

Now we need to start working on the front-end part. For this, will first scaffold the app with SvelteKit so then we can build up on it (add components, page and etc).
