Fix PlatformColor parsing on Android when using dark and light theme

Fixes: #7255

I checked #6618 and it partially exists until this time, like I can't use a primary color like ?attr/colorPrimary if I use material theme (e.g. Theme.MaterialComponents.DayNight) but it might have something to do with this:

Maybe it would be better to completely change this behaviour and always put JSONParser.convert(color) because under the hood the value expects to be of ReadableMap type?

you should not assign PlatformColor value to dark/light, it should replace the whole object since PlatformColor is a native way to achieve dark/light, hence, you define the same value in for example style.xml and style.night.xml and then assign the value to it, not assigning same value for both light and dark which is that what was being done natively.

My original PR: https://github.com/wix/react-native-navigation/pull/7216/files, which demonstrates the usage of the PlatformColor.
