CSAT Widget `aria-invalid` without form submission

[danielclubb]

Hi team,

We think we have found an issue with the CSAT widget implementation.

If we provide an error property in the json config data required to use the widget, we get an accessibility error because the CSAT form has an aria-invalid="true" property by default, without the form having been submitted.

If we remove the error property from the json config data, then the accessibility error goes away, however, the error state is then broken as it does not have an error message to display.

We think this is happening because the template logic of the CSAT component looks for error in the context in order to add/remove the aria-invalid="true" attribute, and when this is provided in the json data, the attribute is added by default.

If the property were to be renamed to errorMessage or something similar that isn't just error we think this would fix it.

Thanks!
