fix: pass query params to OG image ISR function on Vercel

Vercel's ISR `passQuery` defaults to `false`, which strips all query
parameters before passing the request to the serverless function.
This caused the compare page OG image to always render the empty state
because the function never received `packages=zustand,redux` or the
`_query` parameter that nuxt-og-image relies on.

Closes #2431
