Feature - Improve our Banner media on the README

[mrspence]

Description
We need a cleaner banner on our README - the current one is a placeholder for a more suitable GIF.

Outline of solution

• GIF banner
• Wider than tall

I still haven't gotten to this. Time has meant other things have taken priority. Will do my best to achieve this week.

@will-lamerton is focused on other important aspects - this issue is back open for contributors 👍

@mrspence What elements you need in the banner??

1. This bird

2. This UI

3. The sceret chat with AI UI ??

Do I prepare some GIF with all three?

@RONAK-AI647 It's to replace this banner image on our README for the repo (the row of app screenshots)

Really looking for a sensible, beautiful banner that captures what the app offers! Clean, not over the top, but compelling.

Our current banner works, but visually it's a bit noisy and confusing!
