### Steps to reproduce

1. Try to set light or dark mode by the Google Maps JS SDK colorScheme property when using a `cloudMapId`

### Expected results

There is a `colorScheme` property, just like in the JS SDK and the `dart_google_maps` wrapper:

https://github.com/a14n/dart-google-maps/blob/1a598b0305f53a2af3ee1b50d6f9e785f5fa2fb9/lib/src/generated/map/map_options.dart#L24

### Actual results

There is no `colorScheme` property. Thus, maps always default to light mode.

### Code sample

```dart
GoogleMap(
          cloudMapId: "7c22373521b2087b",
          // no such property
          colorScheme:
              MediaQuery.of(context).platformBrightness == Brightness.light
                  ? ColorScheme.Light
                  : ColorScheme.Dark,
          // Style property is ignored when using `cloudMapId`
          style:
              MediaQuery.of(context).platformBrightness == Brightness.light
                  ? _lightMapStyle
                  : _darkMapStyle,
        ),
```
