Differentiating icon between marimo notebook and marimo API

[carsonhu]

Description

Been loving marimo so far. When I have a marimo notebook open as well as multiple tabs on the marimo docs, they all have the same icon so it's difficult to immediately jump back to the correct tab.

Suggested solution

Slightly change the icon on the marimo docs pages.

Ha, good point ...! Perhaps we can close the docs logo in a box. Thanks for the suggestion.
