add a new `onNavigationAborted` hook

[huang-julien]

What problem is this solving

hi 👋

Currently there's no hook when a navigation is being aborted by a false within a beforeEach.

This feature would enhance nuxt/nuxt#21751 by avoiding to create a new nuxt hook which doesn't really make sense and should be a vue-router feature.

Proposed solution

The proposed API would be router.onNavigationAborted((to, from) => void)

Describe alternatives you've considered

This was actually already possible but maybe a bit hidden in docs
