Steer Motors Block documentation defect

[OliviliK]

Describe the bug
The description of the steer ratio parameter is incorrect and incomplete.

To Reproduce
Read the current text

The EV3 Brick steers by using a percentage value of follow for one of the motors. This means that the motor in the turn direction will rotate slower than the other. It is the follower motor and the other motor is the drive motor. The drive motor runs at a percentage of full speed set in speed. The follower motor runs at a percentage of speed of the drive motor. So, it runs at a percentage of a percentage of full speed.

Compare that to the actual behavior of the block.

Expected behavior
The missing information is the reference to the corresponding LabVIEW steering parameter in move steering block . These two parameters have the same impact and only the scales are different. Steer ratio is in range -200 .. 200 and steering is in range -100 .. 100.

In default configuration, when the steer ratio is positive the robot turns clockwise to right going forwards with positive power and turns counterclockwise to right going backwards with negative power. If the steer ratio is negative the robot turns left.

The absolute value of the steer ratio is a percentage controlling how much slower the follower wheel is compared to the driving wheel. With value 0, both wheels turn with the same speed and the robot goes straight. With value 100, the follower wheel is not turning at all and the robot turns around the standing wheel. With value 200, the follower wheel turns in opposite direction than the driving wheel and the robot spins around the middle point between the wheels.

Additional context
The defect in the original text is a description how the steer ratio is a multiplication value when it is a subtraction value. The missing info is a comparison to EV3 programming with LabVIEW. Most the migrating users are coming from LabVIEW environment. The other missing info is the description of turning with negative speed.
