fix: replace deprecated delta_x/delta_y with local_delta.x/y in examples and docs

[Krishnachaitanyakc]

Summary

• Replaces all usages of the removed e.delta_x and e.delta_y attributes on DragUpdateEvent with the correct e.local_delta.x and e.local_delta.y properties across all solitaire tutorial examples, the gesture detector mouse cursors example, and the solitaire tutorial documentation.
• DragUpdateEvent no longer exposes delta_x/delta_y — these were replaced by the local_delta Offset object (with .x and .y attributes), causing an AttributeError when running any of the affected examples.

Fixes #6317

Test plan

• Run any of the solitaire drag-and-drop step examples (e.g., step1.py) and verify that dragging a card works without AttributeError
• Run the mouse_cursors.py gesture detector example and verify dragging works
• Verify the solitaire tutorial documentation code snippets match the updated API

Summary by Sourcery

Update drag handling in solitaire tutorials and gesture detector example to use the current DragUpdateEvent local_delta API instead of removed delta_x/delta_y attributes.

Bug Fixes:

• Fix AttributeError in solitaire tutorial and gesture detector examples by replacing deprecated delta_x/delta_y with local_delta.x/local_delta.y in drag handlers.

Documentation:

• Align solitaire tutorial documentation snippets with the updated DragUpdateEvent local_delta-based API.
