Passing folium.Icon to folium.Marker seems to be broken on main

[martinfleis]

GeoPandas CI is failing with Folium main due to the icon passed to the marker no longer being used.

import folium

fc = {'type': 'FeatureCollection',
 'features': [{'id': '0',
   'type': 'Feature',
   'properties': {'name': 'Vatican City'},
   'geometry': {'type': 'Point', 'coordinates': (12.4533865, 41.9032822)},
   'bbox': (12.4533865, 41.9032822, 12.4533865, 41.9032822)}],
 'bbox': (12.4533865, 41.9032822, 12.4533865, 41.9032822)}

m = folium.Map()
marker = folium.Marker(icon=folium.Icon(icon="star"))
folium.GeoJson(
        fc,
        marker=marker,
).add_to(m)
m

This creates a marker with a star symbol in folium 0.19.4 but uses default on main.

Sorry about that Martin! I made a fix that should hopefully solve this issue.
