[AE] Add category for Clothing Sewing Materials

[ricardotejedorsanz]

It has been flagged [issues/3443] that our current taxonomy lacks a dedicated category specifically for clothing sewing materials. This gap could potentially affect merchants who need to apply state-specific tax exemptions for items like fabric, thread, buttons, and zippers used in clothing construction, as required by New Jersey and Minnesota laws.

Existing categories under Arts & Entertainment > Hobbies & Creative Arts > Arts & Crafts can be a suitable umbrella for these products, but they do not clearly distinguish between general crafting materials and those intended for clothing (see image below). We propose creating a new category: Arts & Entertainment > Hobbies & Creative Arts > Arts & Crafts > Clothing Sewing Materials. This should more accurately denote clothing sewing-related materials and could be expanded in the future as needed or serve as a parent to applicable subcategories such as Craft Fasteners & Closures, Crafting Fibers, or Textiles.

Looks good from a technical side of things.

I trust your judgement here, but generally we should be careful adding things simply because it doesn't fit into a tax category. We don't want our taxonomy system to be become overcomplicated with exceptions.

In this case it seems like it can fit though.

@tyler Yes, I completely agree. These should be exceptions rather than the rule, as it's unlikely we can account for all the different tax groupings across every jurisdiction with a single taxonomy tree.

That's why I wouldn't create further duplication by expanding the available leaves under these categories. A single category can still serve as a valid solution without creating excessive overlaps.
