Fixes #2084, which is an issue introduced by #2068.

We shouldn't have removed self.icon in Marker. It's not directly visible where it is used, so I added a comment to prevent this from happening again.

This still fails if people use the add_child method to add an icon. I am okay with that, but I think we should be aware of it.

Also the render method (roughly lines 430-436) was originally rewritten to allow people to use add_child. If we go back to icon as a member variable, we should make it consistent throughout the class.

Is this waiting for some changes or are we fine with it as is? I am unable to properly see the consequences here so will let you be the judges but I'd love this to be merged to fix geopandas CI.

Ah, sorry it escaped my attention. Will look at it presently.
