Namespace support for ensure_pages_exist

[gsoares98]

Currently, when using Inertia::render('module::page'), I get a component not found error (considering that the resolvePageComponent logic has already been customized in app.ts).

To get around this, I had to do this:

$finder = app('inertia.view-finder');
$finder->addNamespace($this->name, module_path($this->name, 'resources/js/pages'));
app()->singleton('inertia.view-finder', fn() => $finder);

It would be very helpful if there were a way to register a namespace like you can with Blade.
