fix(sveltekit): Add Vite peer dep for proper type resolution (#12926)

Add a simple, optional peer dependency on Vite to
`@sentry/sveltekit` to ensure that it picks up whatever version of Vite
is being used in the specific package it's installed in. This is necessary
because `pnpm` otherwise could resolve the `vite` import to a wrong
version, especially in monorepo environments
