Upgrade expo in examples

[mdjastrzebski]

Summary

Upgraded Expo SDK from 52 to 53 in examples/basic and examples/cookbook. The official expo upgrade command was not available, so a manual dependency update to expo@^53.0.19 and yarn install was performed for both projects.

Test plan

1. Navigate to examples/basic.
2. Run yarn start.
3. Verify the app launches successfully (e.g., in a web browser or simulator).
4. Repeat steps 1-3 for examples/cookbook.
