Using router.on triggers ReferenceError: document is not defined when using SSR

[harmendv]

Version:

• @inertiajs/vue3 version: ^2.0.0

Describe the problem:

When I use the code snippet from the documentation (see below), I encounter a ReferenceError: document is not defined when working with SSR.

import { router } from '@inertiajs/vue3'

router.on('start', (event) => {
  console.log(`Starting a visit to ${event.detail.visit.url}`)
})

Steps to reproduce:

• Add the code snippet to the <script setup> section of a Vue page. (Works with the default laravel breeze scaffold with SSR)
• Build the project.
• Start the SSR server.
• Navigate to the page containing the code snippet.

This should've been fixed in #1715, but I see with 2.x these changes have been reverted due to refactors, I'll look at sending in another PR
