Update UrdfSensorsExtensions.cs

[vidurvij-Unity]

Proposed change(s)

Remove addition of transform sensors while robot import.

Function to add the Transform sensor is still present in RobotSensorExtensions.cs. It's just the function call that has been removed. This will allow us to easily reinstate the feature in the future.
