I am trying to pass additional css classes to the generated ul element. I am applying general formatting via the validation-errors css class, but I would like to be able to pass utility classes for spacing (i.e. pt-2 to add 8px of padding to the top of the validation summary).

Describe the solution you'd like

Update <ValidationSummary /> to pass unmatched attributes (via splatting) to the validation-errors element. In the case of class, it should append the passed in classes to the existing validation-errors class.

Additional context

For example:

<ValidationSummary class="pt-2" data-test="validation-errors" />

should result in:

<ul class="validation-errors pt-2"  data-test="validation-errors">
    <!-- Validation Errors -->
</ul>
