beforeNavigate event

[martynaskre]

Developers who are familiar with Vue router are aware of beforeEnter event, which is useful for a lot of types scenarios, such as lazy loading or modifying the page that will be swapped.

Currently, I am attempting to integrate lazy loading for translations, with the locale being controlled by a Laravel backend. The most straightforward method would involve intercepting the page's locale before the frontend components are switched. Unfortunately, there is currently no available option to accomplish this.

All things considered, this would be nice addition to framework, enabling developers to incorporate different techniques.

If this proposal matches the development direction of Inertia, I would like to contribute a PR for this feature!
