tests: bump `create-vite`

[manuel3108]

We tried bumping create-vite in #1115 but this caused strange side-effects while testing the tailwind integration.

AI summary of our conversation yesterday:

There seems to be a regression/difference in the create-vite template that affects Tailwind spacing utilities.

In one template, mt-1 resolves to 4px, while in the create-vite template it resolves to 4.25px. Initially this looked related to the --spacing CSS variable, but after testing, the actual cause appears to be the template’s global font shorthand:

font: 18px/145% var(--sans);

Because Tailwind spacing utilities are rem-based, setting the root/base font size to 18px scales utilities like mt-1 from the expected 4px to 4.5px / similar values depending on the setup.

This does not happen in the SvelteKit template, so the create-vite template seems to be applying global font styles differently. Updating create-vite was skipped for now because even create-vite@8.3.0 already has this behavior. We likely need to bisect the template changes to see when and why this was introduced.
