Adapts A and D button bindings in the keyboard device (#910)

# Description

While developing some teleoperation methods, I discovered that the
keyboard y-axis was moving in a non-intuitive direction. It turned out
that the +ve and -ve y-axis are bound to keys (D, A) instead of (A, D).
This MR fixes the issue in both keyboard device documentation
instructions to follow the right-hand rule.

## Type of change

- Bug fix (non-breaking change which fixes an issue)
