Update class-redux-page-render.php

This resolves PHP warnings like:
Deprecated: Implicit conversion from float 0.2 to int loses precision

I need you to explain in detail the advantages of this, including a use case that I can try on my end. Too often, people want to mess with the core, and it blows up down the line, which means I have to fix it. So, let's be sure.

Sure @kprovance

PHP ver: 8.1.29
Please try the follow example:

Redux::setSection( $opt_name, array(
    'title'     => esc_html__('Colors', 'option-plugin'),
    'icon'      => 'fa fa-tint',
    'fields'    => array(
      
        array(
            'id'       => 'boxed_site_shadow_color',
            'type'     => 'color_rgba',
            'title'    => esc_html__('Shadow color', 'option-plugin'),
            'subtitle'  => esc_html__('Defines the page shadow. ', 'option-plugin'),
            'transparent' => false,
            'options'       => array(
                'clickout_fires_change' => true,
            ),
            'default'   => array(
                'color'     => $color_1,
                'alpha'     => 0.15
            ),
            'required' => array(
                    array('boxed_fullwidth','equals','0'), 
                    array('boxed_add_shadow','equals','1'),                   
            ),  
            'compiler' => true,
        ),
        array(
            'id'        => 'submenu_background_nav_dark',
            'type'      => 'color_rgba',
            'title'    => esc_html__('Submenu Background Color', 'option-plugin'),
            'subtitle' => esc_html__('Pick a background color for the submenu.', 'option-plugin'),
            'default'   => array(
                'color'     => '#fff',
                'alpha'     => 0.95
            ),
            'compiler' => true,
            'options'       => array(
                'clickout_fires_change'     => true,
            ),                    
        ),
        array(
            'id'        => 'submenu_border_nav_dark',
            'type'      => 'color_rgba',
            'title'    => esc_html__('Submenu links border color (desktop)', 'option-plugin'),
            'options'       => array(
                'clickout_fires_change'     => true,
            ),
            'default'   => array(
                'color'     => '#000',
                'alpha'     => 0.1
            ),            
            'compiler' => true,       
        ),        
    ),
));

Explanation:
Setting 'alpha' default value to 0.1 causes PHP warnings, because it is a numeric value.
Setting it to "0.1" is OK, because it is a string.
But alpha kind of is a numeric value and in my case it was written this way.

It took me a hot minute to figure out why I couldn't reproduce this. It only occurs when the show_default is set to true. Replicated and contributed fix applied (manually) and credited. Much obliged.
