Blake Friedman 4410899ec7 Only cache node_modules on main (#45544)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/45544

## This diff now does 5 things:
1. removes the old way we used `actions/setup-node` to manage the cache itself.
2. it creates a new `update-node-modules-cache` workflow, which is the only job that will update the node modules cache
3. it create a `yarn-install-with-cache` action that should be used install of directly calling `yarn install --non-interactive`.  This will load a cache against a hash of `package.json`.
4. updated the cache reaper to aggressively remove everything but the latest `npm-{{ hash('package.json') }}`.
5. removed a `cache-setup`, which couldn't be used (we're using artefacts now).

## Why are we doing this:
The various `node-cache-` keys for platforms and on various branches accounts for a very large proportion of the cache (10-20%).

We don't frequently change these dependencies, and even when we do running `yarn install` after loading the cache will resolve any issues.

Limiting the cache to `main` and aggressively pruning older cache entries will clean up a lot of "small win" caching.
