Fix(DivIcon): revert #5517 to avoid appending a single node instead of generating content (#5574)

* Docs(Marker): explain checks for re-using icon element

when the marker is modified with an icon of the same type (i.e. an image icon with an image icon, or a DivIcon with a DivIcon), or checks for NOT re-using the icon element when modifying with an icon of a different type (i.e. an image icon with a DivIcon, or the reverse).

* Revert "Div icon accept node element as option (#5517)"

This reverts commit ba7bfb5011.
