Use is_product_category() properly

is_product_category() is to be used on woocommerce category archive pages only so first make sure that you are on category archive.

instead of category number use category slug name is_product_category('category-slug')

no need to run OR(||) condition just use is_product_category('category-slug1','category-slug2') to get same output
