Fix (partially) Svelte E2E test (#6428)

## What's the problem this PR addresses?

The SvelteKit E2E test has been failing

## How did you fix it?

- `create-svelte` discontinued the `next` dist-tag, use `latest` instead
- I don't know how it was but `yes` cannot defeat `create-svelte`
interactivity now, so I just use its node API instead
- Also added a TypeScript test

The test should still be failing due to
sveltejs/kit#11433 (comment), but
at least it is an actual failure of the E2E test, not of our setup.
:shrug:

Closes #6345
