Change project icon

Currently it has the one of the organisation:

<img width="457" alt="Image" src="https://github.com/user-attachments/assets/5b530ff6-58f1-49d3-8e1e-cfca3986eb6c" />

We should use this instead:

<img width="149" alt="Image" src="https://github.com/user-attachments/assets/4cf4f264-76b2-4947-92e4-ebff15c1dac9" />
