Nuno Faria 4d63f8c927 minor: Add favicon (#20000) ...

## Which issue does this PR close?

- N/A.

## Rationale for this change

There is no favicon currently set for the DataFusion site.

For example, when searching on Google:
<img width="228" height="139" alt="image"
src="https://github.com/user-attachments/assets/c0d2cd43-26fb-4715-a10c-0e60b7853a0a"
/>

When a tab is opened:
<img width="257" height="42" alt="image"
src="https://github.com/user-attachments/assets/4deb74b1-f29f-4bb5-a18b-d634e8ac0b16"
/>

Adding the logo makes it look nicer.
