Add 5 long-form (~30s) examples to the Gradio Examples table

Pairs richer multi-beat scenes with gen_duration=30s in the row data so
clicking generates a full half-minute clip:
- 30s • Villain soliloquy (Harvey-Keitel-style)
- 30s • Late-night radio monologue (old-movie host)
- 30s • Stand-up wheeze-laugh (Conan-style)
- 30s • Bedtime story (warm female narrator)
- 30s • Sports commentary (Samuel-J-style)

Existing short examples remain with gen_duration=0 (auto).
