Fix HERMES_ENABLED in react-native-xcode.sh

[janicduplessis]

Summary

HERMES_ENABLED value is currently wrong when running in a normal project setup. When running grep the current directory is the project root directory, which is not where the Podfile.lock usually is ("$rootProject/ios"). To make sure to grep the right folder we can use the PODS_PODFILE_DIR_PATH env provided by Cocoapods.

This looks like a duplicate of #34675 right?

[janicduplessis]

It is, I didn’t see #34675. Funny that we have the exact same fix including the file capitalization change 😅

[janicduplessis]

#34675 landed so this is not needed
