Subject: [PATCH] find-node.sh supports Homebrew on M1 (#31622)

Summary:
Homebrew on M1 installs executable binaries in **/opt/homebrew/bin** (See https://brew.sh/2021/02/05/homebrew-3.0.0/), and FBReactNativeSpec.build is failing because it couldn't find node. This PR changes find-node.sh script to add /opt/homebrew/bin into $PATH.

The way **react.gradle** trying to execute node is not using user environment variables, but system defaults, so it couldn't find it. I removed node execution, and hard coded cli path in parity with iOS https://github.com/facebook/react-native/blob/d1ab03235cb4b93304150878d2b9057ab45bba77/scripts/react-native-xcode.sh#L106

Fixes https://github.com/facebook/react-native/issues/31621 https://github.com/facebook/react-native/issues/31592

## Changelog

[General] [Changed] - find-node.sh supports Homebrew on M1

Pull Request resolved: https://github.com/facebook/react-native/pull/31622

Test Plan: On M1, create a RN project and it'll fail to build iOS app. Apply the patch, and build will succeed.
