Small fix needed

Hello.

I configured your plugin on multilingual website with Polylang. Categories names were translated but products for other languages didn’t show in the tab container.

I looked up in the plugin code and I saw you used
$cat->name here
echo do_shortcode('[product_category category="' . $cat->name . '" per_page=' . $product_number . ' columns=' . $column_number . ' orderby="date" order="desc"]');

I changed to
echo do_shortcode('[product_category category="' . $cat->slug . '" per_page=' . $product_number . ' columns=' . $column_number . ' orderby="date" order="desc"]');

and translated products started to show in other other languages
