[colemanliyah]

Resolves PR #1483 (#1483)

• Replaced all older ml5 examples (ml5.handpose(), modelReady(), predict events, annotations) with the new API:

  • await ml5.handPose()
  • detectStart()
  • keypoints

• Updated every example sketch to work with the current ml5 version:

  • Detecting hand keypoints
  • Printing prediction data
  • Drawing fingertips
  • Adding images to fingertips
  • Moving objects with fingers
  • Controlling multiple objects with multiple fingers
  • Using conditionals with finger positions
  • Creating gesture-based interactions

• Embedded all example sketches directly into the tutorial using instead of linking out to external sketches.

• Added updated comments and explanations to match the new code structure.

• Updated explanations of prediction data to match the new HandPose output format (keypoints, keypoints3D, handedness, confidence).
