fix: use vite@5

Relates #341, #311 (comment)

From vitest-dev/vitest#7014 (comment)

Vitest 2 doesn't support Vite 6 and will not support Vite 6 officially. You can use resolutions or pnpm.overrides to change the version range locally, Vite 6 API is the same and should work for Vitest 2.

If you migrated to Vite 6, use Vitest 3 (currently in beta), release is planned for January.

If you see any type errors in your config, check the lockfile to confirm that you have several Vite versions installed and resolve it with your package manager.
