Subject: [PATCH] feat(controllers): add delete and getBySlug methods in
 category controller

The `category.controller.ts` has been updated to handle deleting a category and retrieving a category by slug. The `deleteCategory` function takes a category slug from the request params and first checks if the category exists before attempting to delete it. While the `getBySlugCategory` function simply retrieves a category by its slug.

Issue: #12
