Internationalization

[nicowitteman]

I was wondering if you might consider making the warning and error messages translatable to other languages than English. I also asked this from Anders Åberg for the FIDO2 library. (passwordless-lib/fido2-net-lib#394)

Makes sense, I will add this, or you can do this in a PR if you want

I'll gladly leave this to you - no idea where to start. I am more than willing to provide the Dutch translations, though.
Thanks, Nico
