Allow html on radio-buttonset choices

[anthonyryanrusso]

Issue description:

Is there a way you can allow html on radio-buttonset choices? I would like to have the actual icon show but it seems to be outputting the choices as plain text.

Version used:

3.0.25

Using theme_mods or options?

theme_mods

Code to reproduce the issue (config + field(s))

Kirki::add_field($opt_name, array(
    'label' => esc_html__('Header middle cart icon'),
    'section' => 'header_middle_setup_section',
    'settings' => 'header_middle_cart_icon',
    'type' => 'radio-buttonset',
    'required' => array(
	array(
	    'setting' => 'header_middle_icons_menu_visibility',
	    'operator' => 'contains',
	    'value' => array('mobile', 'tablet', 'desktop')
        ),
        array(
	    'setting' => 'header_middle_cart_visibility',
	    'operator' => 'contains',
	    'value' => array('mobile', 'tablet', 'desktop')
	)
    ),
    'choices' => array(
        'shopping_cart' => '<i class="fas fa-shopping-cart"></i>',
        'shopping_bag' => '<i class="fas fa-shopping-bag"></i>',
        'shopping_basket' => '<i class="fas fa-shopping-basket"></i>'
    ),
    'default' => 'shopping_cart'
));
