Allow to set a different wikipedia base URL (support for other languages)

This is a genius idea, this app is incredible!

Unfortunately simple wikipedia is only in english. To support other languages, it may be useful to support changing the base wikipedia url. There also exists other children wiki encyclopaedia but they are hosted on other websites (eg, vikidia for french).

In the future, using the adult versions of wikipedias may not be an issue since they could get simplified using AI (there are already local offline models that work on Android, they can be used to transform the text into a simplified and shorter version for kids).
