Use Wan-AI/Wan2.1-T2V-14B as default model for text to video showcase (#1248)

Remove text-to-video HunyuanVideo showcase for now since it can rarely
generate video in less than 2mins. We'll probably replace with Wan 2.1
when active in prod

EDIT: actually Wan2.1 just got enabled, so we can use it 👍
