ArrowSquareUp correction

Corrected the ArrowSquareUp icon in the Vortex Icons library.

Fixed

Corrected the ArrowSquareUp path and alignment so the icon matches the rest of the directional icon family at small sizes. Existing imports continue to use the same icon name and require no code changes.

The correction is contained in the SVG asset itself, so applications receive the improved geometry by updating the package without changing their React markup or icon sizing props.
