Add Vehicles generator

[trinaldi]

Summary

This PR adds Faker::Vehicles::Car with car brand, model and version.

Other Information

I have to deal with a lot of car related info in my job. I was using a few generic generators to create the brand name, model name and version name, so I decided to create this one myself.

The idea behind Vehicles is to insert not only Car but any vehicle in the future (e.g Motorcycle). I believe this namespace will attract another users, enthusiasts, etc..

This is my PR to this project, so let me know how can I improve it.

thanks for sending this PR @trinaldi!

We currently have a vehicle generator that gives you a make, model, transmission, etc.

Is the intent behind your contribution to reorganize this information under a separate namespace so people can add other types of vehicles in the future, or is this unrelated to the existing information we already have?

I think this would be helpful and having other vehicles would be nice too. Although as @thdaraujo pointed out, it would be helpful to know more about the intent.

Also I'm not sure why the tests are failing, that needs to be resolved.

[trinaldi]

To be honest, I wasn't aware of those Vehicles generator, @thdaraujo, my bad.
My intent was to create a new generator category. Knowing that there's already a Vehicle generator, I can just add to the yml file as @psibi pointed out.

I think we can close this PR, then;
