Random Review Shortcode: I had to modify the pastebin code

I tried to use the code from https://pastebin.com/naUae8zB to get a random review shortcode.

• I created a child theme and pasted the code into functions.php.
• Then I tried to use the shortcode [site_review_random].

Expected:
To get a random review.

Current:
Every time I added [site_review_random] anywhere WordPress threw an error in the area where the review was supposed to appear. I can’t really say what went wrong, it might be because I’m on PHP 8.1.

Workaround/Fix
I got the code working by adding $atts = []; in line 14 like so:

add_shortcode('site_review_random', function ($atts) {
    $atts = [];
    $atts['orderby'] = 'random';
    $atts['per_page'] = 1;
    if ($reviews = apply_filters('glsr_get_reviews', null, $atts)) {
        $html = $reviews->build();
        return sprintf('<div class="%s">%s</div>', $html->style, $html);
    }
});

I post this here so it might help others. Thank you for this nice plugin with such a flexible API and thank you, too, for the random review code.
