Geocoder plugin breaks due to renamed CSS file in leaflet-control-geocoder 3.0.0

[g-fabiani]

Describe the bug
When using the Geocoder plugin, the plugin's CSS file fails to load due to a name change in the leaflet-control-geocoder library from version 3.0.0.

Folium still references the outdated file at https://unpkg.com/leaflet-control-geocoder/dist/Control.Geocoder.css, but in version 3.3.0 the file has been renamed to leaflet-control-geocoder.css. This results in a 404 error and the Geocoder widget is displayed incorrectly (missing styles).

To Reproduce

import folium
import folium.plugins

m = folium.Map()
folium.plugins.Geocoder().add_to(m)
m.save('map_with_geocoder.html')

1. Run the code above.
2. Open the generated map_with_geocoder.html file in a browser.
3. The geocoder widget is displayed incorrectly and the geocoder stylesheet is missing.

Expected behavior
The correct CSS file (leaflet-control-geocoder.css) should be loaded, and the Geocoder widget should display with the expected styles.

Environment (please complete the following information):

• Browser firefox (133.0.3), chrome (131.0.6778.139)
• html files
• Python version 3.10.15
• folium version 0.16.0
• branca version 0.7.1

Additional context
The issue originates from the leaflet-control-geocoder library.

• In version 3.0.0, the CSS file Control.Geocoder.css was renamed to leaflet-control.geocoder.css.
• Folium still references the old file name

Possible solutions
Update default_css in the Geocoder class to reference https://unpkg.com/leaflet-control-geocoder/dist/leaflet-control-geocoder.css
