chore: Vite to ^2.4.3, vite-plugin-svelte to ^1.0.0-next.13

[GrygrFlzr]

• Vite 2.4.3 introduces fixes for TailwindCSS, so despite the ^2.4.1 matching its semver we should explicitly raise the minimum.
• Update @sveltejs/vite-plugin-svelte

Tests

• Run the tests with pnpm test and lint the project with pnpm lint and pnpm check
