Add smooth‑stone&terracotta stairs to complete 26.3 stair‑block collection

napshot 26.3‑7 has satisfied countless builders by releasing concrete stairs, concrete slabs and colourful wool stairs.
I sincerely hope the team keeps this wonderful update trend.
Smooth‑stone slabs have existed for many years without matching stairs, and all dyed terracotta variants lack stair‑shapes.
Players can currently work around this limitation via trap‑doors and panels. New stair variants are merely more building selections instead of locking one fixed construction method.
These blocks will be perfect for decorating custom‑built abandoned woodland camps together with layered birch‑tree mushrooms and cushions.
