Allow URL override by defining a URL resolver

[rojtjo]

This pull request provides an alternative solution to @FrittenKeeZ's pull request ( #499) by allowing you to configure a callback that resolves the current URL. This way it can be easily configured to anyone's needs by overriding the urlResolver method in the HandlesInertiaRequests middleware. When this method returns null it falls back to the default behavior.

Example:

use Inertia\Middleware;

class HandleInertiaRequests extends Middleware
{
    public function urlResolver(Request $request): ?callable
    {
        return fn (Request $request) => 'https://inertiajs.com/'.$request->getRequestUri();
    }
}

@rojtjo This is an elegant solution to fix broken URLs when the application is inside a sub-directory.

When can we expect to get this solution merged?

Would really like to see this merged! Thanks @rojtjo for your great work! I think this could also solve running Laravel Nova 4.x in a subdirectory (based on inertia, broken at the moment).
