unnecessary code in "Migrating to Modern Asset Formats: glTF and KTX2" chapter

[mewingchessmogger]

code below is present in tutorial. gltf already has a optimized vertex buffer for index buffer. No need for checking unique vertices
...

            // Add vertex if unique
            if (!uniqueVertices.contains(vertex)) {
                uniqueVertices[vertex] = static_cast<uint32_t>(vertices.size());
                vertices.push_back(vertex);
            }
        }
