Subject: [PATCH] Enhance IP address retrieval for iOS devices in Metro bundler
 setup (#41839)

Summary:
After introducing this commit https://github.com/facebook/react-native/commit/a56e5dad7c31b6e9e6b02333219bc33811215056 script may fail in some circumstances.

Example:
When there is IP address available only for en1 and not en0, first "ipconfig" command in the loop fails with error code 1 and cancels whole script.
