[BUG] Setting the 'documentation' property on a custom control builderInfo has been broken at some point after 4.11.3

Environment

Please provide as many details as you can:

• Hosting type
  • [] Form.io
  • [x] Local deployment
    • Version: 4.14.8

    static get builderInfo() {
        return {

    }
