Road: Markings

• Replaced side lines with V shaped markings
• Slight adjustments to arrow markings
• Reordered textures to follow 1.20+ creative inventory order

Note: If you're working with older builds (from 1.14–1.19), some markings may appear mismatched. You can continue using v1.0.0, as it still works perfectly fine since most of the textures haven’t changed.
