fix(ci): Set REACT_NATIVE_NODE_MODULES_DIR for Expo SDK 54 builds

Expo SDK 54 upgraded to React Native 0.81, which uses the new Hermes profiling API. In the monorepo, the Sentry SDK's podspec was detecting RN 0.80 (from packages/core/node_modules) instead of 0.81 (from samples/expo/node_modules), causing it to use the old Hermes API which was removed in RN 0.81.

Setting REACT_NATIVE_NODE_MODULES_DIR ensures the podspec detects the correct React Native version during CI builds.

This only affects the CI build - no changes to the core SDK.
