Fix : Missing init key for maptiler and update style

[ravenfeld]

It's quite strange that the examples don't work. It doesn't help developers.
Let's start by making sure it doesn't crash any more

#62

I suggest that we replace the styles with styles that do not require an API key.

For example:

https://tiles.openfreemap.org/styles/liberty

https://tiles.openfreemap.org/styles/positron

https://tiles.openfreemap.org/styles/bright

https://tiles.versatiles.org/assets/styles/colorful.json

https://americanamap.org/style.json

Should I still use WellKnownTileServer and getPredefinedStyle?
Because I don't know much about it as I don't use it on my personal project.

I would not use them, because we will remove them at some point from MapLibre Native.

I created a TestStyles.kt file for MapLibre Native: https://github.com/maplibre/maplibre-native/blob/main/platform/android/MapLibreAndroidTestApp/src/main/java/org/maplibre/android/testapp/styles/TestStyles.kt

[ravenfeld]

enum class OpenFreeMapStyle(val url:String){
    POSITRON(url = "https://tiles.openfreemap.org/styles/positron"),
    BRIGHT(url = "https://tiles.openfreemap.org/styles/bright"),
    LIBERTY(url = "https://tiles.openfreemap.org/styles/liberty")
}

Here's what I suggest. So we use this enum instead of getPredefinedStyle

I like TestStyles class better, might be that we have to replace OpenFreeMap with something else...
