Update climber sequence

[Nick-P-Orr]

Mechanically some things have changed on the robot. We need to make a few changes to the climber sequence.

• [ ] Remove step to bring hooks down on high bar (the extra material was removed)
• [ ] When the intake hook is on the traversal bar, pull in slightly to ensure the main climbing arms releases from the high bar
• [ ] Remove need to push button to step through
• [ ] Add 'stop' button incase theres an issue when climbing, and then allow it to be re-pressed to continue
