* Lower minimum Node.js version to 20.19.4 (#52678)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52678

From partner feedback, there's still appetite to support Node 20.x for the next <1y of life. Lower min version to `20.19.4` (Jul 2025) and widen test matrix in CI.

Changelog:
[General][Breaking] - Our new minimum Node version is Node.js 20 (Overrides #51840)

* Bump Metro to ^0.83.1, lower minimum Node.js version to 20.19

Summary:
Metro release notes: https://github.com/facebook/metro/releases/tag/v0.83.1

The only public-facing change is a lowering of the minimum Node.js version from 22.14 to 20.19.

This will need picking to RN `0.81-stable`

* Do not setup-node twice in test_js (#52737)

Summary:
I've noticed that test_js (20) and test_js (24) are actually running on Node 22.
That's because the `yarn-install` action is invoking setup-node again with the default value (22).

This changes it. Also I'm cleaning up the workflows so that every `yarn-install` invocation is happening just after the `setup-node` invocation.

## Changelog:

[INTERNAL] -

Pull Request resolved: https://github.com/facebook/react-native/pull/52737

Test Plan: CI which will most likely be red for test_js (20) so will need a follow-up
