Fix unhandled match cases in AiModelCapability.php

UnhandledMatchError: Unhandled match case Drupal\ai\Enum\AiModelCapability::ImageToImageUpscale in Drupal\ai\Enum\AiModelCapability->getBaseOperationType() (line 48 of modules/contrib/ai/src/Enum/AiModelCapability.php).

I think this case (and the other ones in this file) should be handled
