Update category.php

This line 108 giving error:
Unknown: html_entity_decode(): Passing null to parameter opencart#1 ($string) of
type string is deprecated in
/home/upload/catalog/controller/product/category.php on line 108

When i asked Journal theme support they suggested  these changes adding these ( ?? ''  before  , ENT 

if ($category_info['image'] && is_file(DIR_IMAGE . html_entity_decode($category_info['image'], ENT_QUOTES, 'UTF-8'))) {
with

if ($category_info['image'] && is_file(DIR_IMAGE . html_entity_decode($category_info['image'] ?? '', ENT_QUOTES, 'UTF-8'))) {

and now this is working.
