Replace react-navigation imports

In order for us to display environment banners and service messages on all screens, you need to import createNativeStackNavigator/createBottomTabsNavigator from @equinor/mad-core instead of react-navigation. Currently we don't support other navigators. Do you need support for other navigators? Create an issue!

By default environment banners and service messages should display if the screen header is displayed. If you need to override this behaviour, you can use the customSubHeaderShown option. For more information on using customSubHeaderShown, refer to @equinor/mad-navigation's documentation.

Using @equinor/mad-core's NavigationContainer is optional, but it adds application insights navigation tracking for you automatically, which is a nice feature to have!

import {
    createBottomTabNavigator,
    createNativeStackNavigator,
    createNativeStackCoreNavigator,
    NavigationContainer,
} from "@equinor/mad-core";
