Regression from PR #47458: Cannot install React Native from Git anymore

Description

This PR updates shouldSkipGenerationForRncore as such it checks if .../ReactCommon exists before deciding to skip rncore generation, whereas previously it would check .../ReactCommon/react/renderer/components/rncore specifically.

This change breaks installations from Git.

I noticed this while upgrading from 0.76.2 to 0.78.1.

Per my debugging:

• Previous behavior:
  • When installing from NPM: rncore is pre-generated using the prepack script
  • When installing from Git: rncore gets generated when running pod install
• Current behavior:
  • When installing from NPM: rncore is pre-generated using the prepack script
  • When installing from Git: rncore will NOT get generated when running pod install because .../ReactCommon is detected as exists even though .../ReactCommon/react/renderer/components/rncore does not

Steps to reproduce

npx @react-native-community/cli@latest init BuggyReactNative
cd ./BuggyReactNative/
npm install 'https://gitpkg.vercel.app/facebook/react-native/packages/react-native?0.78-stable'
cd ./ios/
bundle exec pod install
cd ..
ls ./node_modules/react-native/ReactCommon/react/renderer/components/rncore
# 💥 no such file or directory

Commencez dans packages/react-native/scripts/codegen/generate-artifacts-executor.js, au niveau de shouldSkipGenerationForRncore, et comparez le comportement antérieur référencé avec la vérification actuelle de ReactCommon. Utilisez le reproducer de l’installation via Git de l’issue et bundle exec pod install pour vérifier le chemin de génération. C’est terminé lorsque le répertoire rncore existe après l’installation et que le projet iOS peut être compilé.
