FEATURE - Add Properties to `Vehicle`

[Mikaela Caron]

Describe the feature you want the app to have that it currently doesn't

• Add these properties to the Vehicle model, they are all strings
  • year
  • color
  • VIN
  • licensePlateNumber

Describe alternatives you've considered

• N/A

Additional context

• You will need to update the AddVehicleView and the SettingsView where the vehicles are listed
• You can't update vehicles yet because that is part of #5
