docs: fix description of generated file

[ivanhofer]

I tried running the kit.svelte.dev project and immediately got greeted by an error message because type-info.js was not found.
It took some time to figure out how to generate it because the description was not up to date. This PR fixes it.

Made a fix: now uses pnpm instead of npm

[PuruVJ]

This should be run in dev command, like svelte.dev. could you add it there?

@PuruVJ done

LGTM! Approved, although that doesn't mean anything on this repo, someone with merging rights need to merge 😁

FYI, this appears to have broken site deployments. We don't want to use pnpm update, because that doesn't just run the update script. It attempts to actually upgrade dependencies, which is wreaking all sorts of havoc. I've opened #10431 to use pnpm run update rather than pnpm update.
