refactor: migrate to svelte ts for API example

[Legend-Master]

Since we already have the checkJs enabled, might as well just migrate to typescript so I don't get vscode marking every svelte file as having type errors

disclosure: initial migration was done through codex to save me some typings

I feel like every HTML based custom language I have used all suffer from more or less a subpar editor experience, some syntaxes don't work sometimes and all that, and the formatters are especially bad. And we are on Astro and Svelte 😂 I must say I had a much better experience with JSX based frameworks like React and SolidJS
