Graphic ideas
Since it is a subproject of moonrepo, we could use the same icons.

Additional context
Since the folder .proto is more often use for protobuf files, I think we should not add that association. I'm still writing it in this issue because if we add a new icon instead of using the one from moon, we could add a folder icon and let the user use it in their settings.
