Added support for Htmlable contents in BaseElement

I've recently update to laravel/framework 10.19.0 and noticed that it breaks on of my components.
Error message is: The given child should implement Spatie\Html\HtmlElement or be a string

My component looks like this:

<!-- Send button -->
<div class="row form-group text-center">
    <div class="col-lg-12">
        {{
            html()
                ->submit($slot)
                ->class(['btn', 'btn-primary'] + (($disabled ?? false) ? ['disabled'] : []))
                ->class($class ?? [])
                ->id($id ?? 'submit')
                ->attribute(isset($form) ? 'form' : '', $form ?? '')
                ->disabled(($disabled ?? false) ? "disabled": "")
        }}
    </div>
</div>

And i use it like this:

@component('fc::submit')
       {{ __('save') }}
@endcomponent

This is my fix for the problem. also reported here: #193

Could you remove the code styling changes from this PR so the actual change is visible?
