feat(modules/lib): getVehicleModName and getVehicleLiveryName

[mafewtm]

Description

Adds a function to get the vehicle mod name and vehicle livery name. Came across a use for it and realized we didn't have it in our lib so I figured I'd toss it in here. Not sure what everyone else's options on it are.

Failing linter until https://github.com/iLLeniumStudios/fivem-lua-lint-action/pull/16 is merged
