Hotkey - Ayyubids "Siege Carpentry” Upgrade in Siege Workshop - Missing separate hotkey and uses the wrong Abbasid “Upgrade Camel Support” hotkey in Fully Remappable Layout

For Ayyubids, the unique upgrade “Siege Carpentry” in the Siege Workshop is in the “S” spot, but uses the default “X” hotkey for “Upgrade Camel Support” from the House of Wisdom instead.

Fix: Make new Siege Workshop hotkey for “Siege Carpentry”.
