Current behavior

The second config cleanupAttrs is specified at the same place as the first config. It's not correct.

Expected behavior

Each config should become each item ie

"svgoConfig": {
      "plugins": [
        {
          "removeDimensions": true,          
        },
        {
          "cleanupAttrs": true
        }
      ]
    }

Minimal reproduction of the problem with instructions

What is the motivation / use case for changing the behavior?
