[bug] removeDefaultStyles does not remove default styles on ResponsiveGrid

[cjwiseman11]

Describe the bug
Adding removeDefaultStyles to ResponsiveGrid does not remove styles.

Ref: https://github.com/adobe/aem-react-editable-components/blob/master/src/components/ResponsiveGrid.tsx#L45

  if (isInEditor || !props.removeDefaultStyles) {
    className = `${className} ${props.gridClassNames || ''} ${ClassNames.CONTAINER}`;
  }

The code here shows that isInEditor will always return true and it seems impossible to override gridClassNames prop.

We want to use a custom grid but this is forcing our hand.

Package version
2.1.1

To Reproduce

1. Add removeDefaultStyles to ResponsiveGrid

Expected behavior
Grid styles removed in AEM
