Summary: Copilot adds voice conversation feature

Why It Matters: This change makes Copilot feel more like talking to a person. It could make using Copilot easier for some people.

What Changed:

• The main headline changed from "Microsoft Copilot: Your AI companion" to "A face you can talk to Start a voice conversation to see my new look."
• The greeting changed from "Hi there. What should we dive into today?" to "Hey, nice to see you. What’s new?"
• New text "A face you can talk to Start a voice conversation to see my new look. Try it" was added.
• Several quick response prompts like "Create an image," "Write a first draft," and "Design a logo" were removed.
