typescript errors in svelte components are not found by lints

[MrGreenTea]

When running pnpm run lint it seems typescript errors are not found in .svelte files. Check this out.

I found this while working on #448 and the small refactoring of the image type of the yearly events.

This is shown in my nvim editor when opening the commit c1a994f

But running pnpm run lint or pnpm exec tsc both do not show any output.

I found this in the astro docs.

Seems we need to use svelte-check as well.
