Configuration ignored when defined in multiple sources

Hi.

The plugin configuration is ignored when it is defined in multiple sources. For example, I set the next two config values in .prettierrc

    "braceStyle": "1tbs",
    "singleQuote": true

but the plugin reports the following Resolved config:

{
  "parser": "php",
  "phpVersion": "7.4",
  "plugins": [
    "@prettier/plugin-php"
  ]
}

Then, I noticed I also had some "prettier": {...} configuration in package.json. The new configuration was still ignored after I added the same two config values to the Prettier property in this file. At this point, both configuration sources are the same.

Finally, the new configuration was in effect after I deleted the .prettierrc file.

Empieza reproduciendo la configuración usando tanto .prettierrc como la propiedad "prettier" en package.json; después, compárala con el caso en el que se elimina .prettierrc. Rastrea cómo se resuelven estas dos fuentes y verifica que braceStyle y singleQuote se conserven cuando ambas fuentes los definan.
