Updating routes to use configurable nova:api group.

[tommulroy]

We noticed the middleware on the API route wasn't using the configurable nova:api group. I'm not 100% sure why not, if there's a reason please can you let me know?

It was causing issues for us with Sanctum + Jetstream.

From config/nova.php

'api_middleware' => [
    'nova',
    Authenticate::class,
    Authorize::class,
],
