fix: pass nonce to next/script properly (#56995)
### What?

This fixes an issue where the `nonce` attribute isn't set on
`next/script` elements that has the `afterInteractive` (the default)
strategy resulting in `<link rel="preload" as="script"/>` tags without a
nonce.

### Why?

For apps that uses 3rd party scripts (or any script) with a nonce loaded
via `next/script` this is necessary unless you want them all to use
`beforeInteractive` which isn't super nice for performance.
