Force tankHealth & oilLevel to be float values to fix leaking issue

[jrgrimshaw]

Description

We are getting a lot of reports of issues with fuel leaking especially; this seems to be due to SetVehicleProperties not forcing these values to be a float. Some scripts may write to the vehicle props JSON directly and set the float fuelTankHealth to an integer value of 1000, and people are incorrectly blaming QBCore for this.

These changes will safeguard players from this potential issue.

You can replicate this easily yourself by running the following - your car will instantly start leaking fuel. This doesn't happen when running the same code with the value 1000.0 instead of 1000.

local vehicle = GetVehiclePedIsIn(PlayerPedId(), false)
SetVehiclePetrolTankHealth(vehicle, 1000)
