MRTK - Leap Motion hand not tracking constraint palm up

[sdudasko]

Describe the bug

When I attach the hand menu to a hand and enable it with HandConstraintPalmUp component it works fine with simulated hand but I cannot make it work with MotionLeap. I am using LeapMotion configuration profile, I also added LeapMotionArticulatedHand controller.

I was trying to debug it and I found out that the code is stuck here - in the file HandConstraintPalmUp.cs

if (!controller.IsPositionAvailable)
{
    // A fully populated hand controller will have position    
    // information available.
    return false;
}

Those lines of code always return false for me and I am not sure why. When working with LeapMotion hands at other tasks, such as basic manipulation with objects, everything seems to work fine.

To reproduce

Steps to reproduce the behavior:

1. Initialize MRTK on the scene with LeapMotion (modules version 4.5.1)
2. Set up a basic hand menu where you expect it to open on palm up with component (HandConstraintPalmUp)
3. Try to open it by rotating your hand - this step does not work for me (only if I quick-fix it by commenting lines above)

Expected behavior

The hand menu should open by using this solver.

Your setup (please complete the following information)

• Unity Version 20.3.29f1
• MRTK Version v2.7
• Leap modules 4.5.1

Target platform (please complete the following information)

• HTC Vive with leap motion controller with the orientation of setting leap on Vive

I think this was fixed in #10446.
