Please change the error-text to match Nova classes and type

Please change the element classes, and type, on the help-text/error-text.
It is much easier to set custom styles if the classes and type, are the same as in Nova.

In your component the error and help text is:
````
<p class="my-2 text-danger"></p>
````
In Nova field components the error-text is a `<div>`.
````
<div class= "help-text error-text mt-2 text-danger"></div>
````
