fix: <Script> with beforeInteractive strategy ignores additional attributes in App Router (#59779)

### What?

Currently, `next/script` in the App Router does not behave as the docs
describe in the [Additional
Attributes](https://nextjs.org/docs/app/building-your-application/optimizing/scripts#additional-attributes)
section – it does not pass on all additional attributes when
`strategy="beforeInteractive"`
([#49830](https://github.com/vercel/next.js/issues/49830)).

### Why?

The props from the `<Script>` component were not passed on to the
underlying script loader (`self.__next_s`).

### How?

I've added the missing props to the object that is `push`ed to
`self.__next_s`.
