Summary:
This PR adds a safety check in case the Cocoapod build script is not able to clean the build folder.
We had evidences where this process failed, and in this way the user has a clear and actionable message to fix its situation.
## Changelog
[iOS][Added] - Add message with instructions about what to do if the cleanup of the build folder fails.
Pull Request resolved: https://github.com/facebook/react-native/pull/35642

I was not able to reproduce the issue locally.
The fix is not destructive, let's see if the amount of issues decreases.
