fix: lock react on 19.0.0 for example project

[draggie]

Summary:

I have noticed during last tests that local version of example app was throwing error in console regarding mismatch between React and React Native renderer version, cause we had loose assign in dependencies for React - so it installed on clear setup the 19.1.0 instead of expected for this React Native version React 19.0.0

Test Plan:

Run android version locally on clear node_modules, check console - no errors should be seen
