[10.x] Make Vite throw a new ManifestNotFoundException

[innocenzi]

What

This pull request introduces a new ManifestNotFoundException that simply extends \Exception.
It's used instead of the base \Exception that is thrown when the Vite manifest cannot be found.

Why

I have specific exception handling in all my projects using Inertia or Hybridly: I don't want to display my custom error page for this error, since it won't be able to be rendered due to Vite not being started.

I currently use the following:

protected function shouldRenderInertiaResponse(Response $response, Request $request, \Throwable $e): bool
{
    if (str_contains($e->getMessage(), 'Vite manifest not found')) {
        return false;
    }

    if (app()->environment($this->skipHandlingInEnvironments())) {
        return false;
    }

    return \in_array($response->status(), $this->httpStatusesToHandle(), strict: true);
}

I believe having a specific exception would make this kind of logic more reliable. This is not specific to my projects' exception handling, it could also be used in Ignition as well, for instance.
