[ios][prebuild] add release/debug switch script

Fixes #T228219721 This commit adds the debug/release switch script like we have for rn deps and hermes for react-core prebuilt: - Added script: replace-rncore-version-js - Inserted script into React-Core-prebuilt podspec - Updated rncore.rb with correct filenames
[ios][prebuilt] fixed using continue in loop
