Missing help Text feature

[tassilogroeper]

Thank you for providing this nice package.

I found myself wondering, why the basic help text feature was not working. When using this field as the other basic fields from nova, the help function does not yield any result.

e.g.

            Checkboxes::make('My Checks')
                ->help('Please tick one of the boxes') // not visible in the frontend
                ->options([ 1 => 'one', 2 => 'two']),

Looking into resources/js/components/FormField.vue:2, the default-field-tag is missing the attribute show-help-text and provide it with the showHelpText-variable coming from the FormField-mixin.

<default-field :field="field" :errors="errors" :show-help-text="showHelpText">

Please update the vue component accordingly.

Thanks
