Rob Hogan c9c601d61a Node.js: Drop support for Node.js versions released before 20.19.4, and EOL v21,v23 (#55114)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/55114

Our official [docs](https://reactnative.dev/docs/set-up-your-environment#node--watchman) require:

> Node 20.19.4 or newer

Currently, our `package.json#engines` fields express this as `"node": ">= 20.19.4"`

This is a bit imprecise because of Node's overlapping release lines - e.g. v24.0.0 is actually older than v20.19.4 (2025-07-15), and the whole v21 line was already EOL before v20.19.4.

The release *date* is relevant because Node.js frequently backports the most important updates - notably, `require(esm)` is already stable in Node 20.19 but is not unflagged in v22 until v22.12.

This makes the `package.json#engines` requirement truer to the documented requirement, dropping some old minors and EOL majors that prevent us using features included in v20.19.

Notably, `require(esm)` is stable and unflagged on all versions supported from this diff.

 - v21 and v23 are EOL, so are dropped.
 - v22.13 pre-dates 20.19.4 and is the first to have unflagged silent `require(esm)`
 - v24.3.0 pre-dates 20.19.4 and is the first to unflag TS-stripping
 - Support v25 and newer.

Changelog:
[General][Breaking] Drop support for EOL Node.js lines and old minors.
