Support PNPM and workspace setups with pod install (#36485)

Summary:
With Metro symlink support coming soon, users will expect isolated `node_modules` resolution and hoisted `react-native` to work. Currently, we make some fragile assumptions in Ruby scripts about the location of `node_modules` packages - in particular `react-native` and `react-native-community/cli-platform-ios`.

This change invokes `node` to resolve those paths, which should allow these scripts to work in any Node JS-compliant setup.

There's a small (sub-second) performance penalty involved in invoking node, but two of these in the context of `pod install` seems reasonable. Also, these scripts [already invoke `node`](https://github.com/react-native-community/cli/blob/fb78fe8ea2fabe8e6d43f5042ecbb92e8e484e12/packages/cli-platform-ios/native_modules.rb#L26), so this isn't an additional dependency or point of failure.

*This is probably the first Ruby I've written in >10 years, review suggestions welcome!*

Changelog:
[iOS][Added] - Support workspace and isolated setups with `pod install`

Pull Request resolved: facebook/react-native#36485

Test Plan: `pod install` succeeds on a PNPM workspace setup where `react-native-community/cli` was not at the path previously expected by this script.
