@wordpress/block-library peer dependency maximum react version is 18

[bpkennedy]

Description

I expect in a project with :

// package.json
{
  "name": "deleteme",
  "version": "1.0.0",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "description": "",
  "dependencies": {
    "react": "^19.0.0",
    "react-dom": "^19.0.0"
  }
}

To be able to install the @wordpress/block-library package:

npm install -D @wordpress/block-library

Expected outcome: it installs without issue.
Actual outcome:

╰─ npm install                                                                                         ─╯

Can this package be changed to support React 19?
