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

Nadie ha tomado este issue todavía.

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`](https://github.com/loadsys/CakePHP-ConfigReadShell/blob/7a4a69d0f65c3ba70f8eccb0c768becacf32dd6a/composer.json#L4) into that (tracked) folder.

It's not clear to me how to detect whether this plugin is being `composer install`ed 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](https://github.com/loadsys/CakePHP-ConfigReadShell/blob/7a4a69d0f65c3ba70f8eccb0c768becacf32dd6a/composer.json#L25) 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`.

Comienza con composer.json, especialmente con la entrada de composer/installers alrededor de la línea referenciada, y reproduce la instalación desde otro proyecto que requiera loadsys/cakephp-config-read:~4.0. Confirma que la dependencia no es necesaria para la configuración master/4.x y, a continuación, verifica que composer install ya no cree una carpeta Plugin/ en la raíz ni instale allí paquetes cakephp-plugin.
