Published version on npm pulls in React 19

We have a React 18 project and adding `@grapesjs/react` pulls in React 19 even though `package.json` correctly has `"react": "^18.0.0 || ^19.0.0"` as a peer dependency.

https://github.com/GrapesJS/react/blob/main/packages/grapesjs-react/package.json#L34

The published package on npm has react@^19.0.0 listed as a regular dependency though
```
$ npm view @grapesjs/react dependencies --json
{
"react": "^19.0.0",
"react-dom": "^19.0.0",
"@types/react": "^19.0.0",
"@types/react-dom": "^19.0.0"
}
````

从 packages/grapesjs-react/package.json 中链接的 peer-dependency 条目开始，然后使用 `npm view @grapesjs/react dependencies --json` 将其与已发布的元数据进行比较。当已发布的包不再将 React 19 作为常规依赖安装，并且符合预期的 React 18/19 peer-dependency 范围时，即表示完成。
