v5.8.3

What's Changed

• Implemented prevention of duplicate attribute slug values. Previously, attribute values with variations in their representations, such as Black and Black", resulted in duplicate entries in the tweakwise_attribute_slug table. This duplication could disrupt filter functionality if the incorrect value was retrieved. This pull request addresses the issue by appending a unique identifier ("-") followed by a number to each slug, ensuring their uniqueness. Note that attributes with previously duplicated slug values will require re-saving to activate this fix. by @ah-net in #159

• Resolved a notice issue pertaining to missing variables when the shopping cart is empty. Previously, certain sections of the application would trigger notices due to uninitialized variables when the cart was empty. by @ah-net in #157
