[frameworks][examples] Add support for zero-config SvelteKit (#6482)

Browse Source 
While we already have support for [SvelteKit](https://sveltekit-delta.vercel.app) on Vercel with the [File System API](https://vercel.com/docs/more/adding-your-framework), this makes the Svelte logo show up and adds an example. I also updated the Svelte example to match their default template and guide the user to use SvelteKit if they want functions.
