Bump motion from 12.38.0 to 12.40.0 in /docs

[dependabot]

Bumps motion from 12.38.0 to 12.40.0.

Changelog

Sourced from motion's changelog.

[12.40.0] 2026-05-21

Added

• path option to transition.
• arc() for motion along an arc.

[12.39.0] 2026-05-18

Added

• Support for repeatType and repeatDelay in animation sequences.

Fixed

• Variants: Re-run keyframe animations when switching between variant labels even when they share identical keyframe arrays.
• Drag: Preserve in-flight motion value animations across React 19 reorder unmount/remount so dragSnapToOrigin no longer leaves the drag transform stranded after a layout swap.
• LazyMotion: Share React contexts between the framer-motion and framer-motion/m (and therefore motion/react and motion/react-m) CJS bundles so that <m.div> from the /m subpath picks up features loaded by <LazyMotion> from the main entry point.
• useScroll: Support hydrating target and container refs from anywhere in the tree.
• Drag: Gesture no longer starts from incorrect start point when rendered inside <AnimatePresence initial={false} />.
• Drag: dragConstraints, when set as viewport-relative ref, no longer break on scroll.§
• Updated visualElement hydration order.
• useAnimate: Now respects skipAnimations.
• AnimatePresence: Fix object-form initial values not applied on re-entry after exit completes.
• scroll: Fixed callback progress when tracking an element.
• useScroll: Fix hardware acceleration when tracking an element.
