Probably don't need `composer/installers` under composer v2?

Seems like this might be the cause of composer install creating a /Plugin root folder and installing every package that has a type: cakephp-plugin in their own composer.json into that (tracked) folder.

It's not clear to me how to detect whether this plugin is being composer installed via composer v1 or v2, but on the master / 4.x branch it's probably safe to remove composer/installers from the composer.json file in THIS project.

The issue is fixed when a different project that runs composer require loadsys/cakephp-config-read:~4.0 should NOT end up with a root Plugin/ folder when running composer install.

从 composer.json 开始，尤其关注引用行附近的 composer/installers 条目，并从另一个需要 loadsys/cakephp-config-read:~4.0 的项目中重现安装过程。确认该依赖项对于 master/4.x 设置并非必需，然后验证 composer install 不再在根目录创建 Plugin/ 文件夹，也不再在那里安装 cakephp-plugin 软件包。
