Fix regex for capturing category and product IDs

The issue was that for product categories with the second or third word
starting with the letter "c," the regex used would capture the wrong
part of the string, leading to incorrect ID extraction.

For example, for the category "Wireless charger," the slug
"wireless-charger-c12345678" would result in "harger-c12345678" as the
ID instead of "12345678." The same issue occurred for products.

This commit fixes the regex to correctly capture the IDs.
