feat(react): add FeedbackSentimentEmojiPicker component with hover bounce

[just-tanvi]

This PR adds a reusable FeedbackSentimentEmojiPicker React component to the EaseMotion React examples.

The component supports both controlled and uncontrolled usage, includes keyboard navigation and accessibility features, and uses EaseMotion hover bounce animations for interactive feedback. It is self-contained, has no dependencies outside React, and is ready to be copied into other projects.

I also added a README with installation instructions, available props, and usage examples.

closes #27371
