Add more European makes and models for the Vehicle provider

[jaapcoomans]

The current lists of vehicle makes and models did not include many cars that are common in Europe. As discussed in #350.
Extended the lists in vehicle.yml based on some resources on best selling cars in Europe of the past few years.

Changed test assertion to accept Citroën and Mercedes-Benz as valid values.

Awesome! Thanks. Seems the test doesn't like VW Id.4 though

Indeed, I missed some test patterns. Fixed it 👨‍🔧

Thanks Jaap for this pr! Btw, seems our random testing isn't so bad ;-)
