Add a fallback for humanizer localization lookup failures

[nyquillerium]

Fixes #5279

At the moment, there seems to be some internal failure on Xamarin/Mono/Humanizer's part to do two things:

• Copy the required language satellite packages to the APK.
• Fallback to the default package if a culture cannot be found.

In either case, it might be good to have a local fallback, so this PR introduces a helper function that catches exceptions thrown by humanizer that are a result of a failure to find a localization.

This was tested on an Android device and seems to be working fine.

There has to be a better way of doing this, because what you've done here is not going to handle all humanizer cases... E.g. you've missed .Pluralize.

Also please give links tracking the aforementioned issues, xamarin and/or humanizer.

[nyquillerium]

We can also potentially initialize a list of loaded localizations for humanizer at startup and checking against those instead, which would allow us to implement our own TryGetCulture method or similar.

Have you tried including the package reference in the android project? Humanizr/Humanizer#380 (comment)

[nyquillerium]

yes, thats the first thing I tried actually.

This needs some kind of resolution.

Going with this for now as a "don't have a better idea" temporary fix.
