Let \( y = y(x) \) be the solution curve of the differential equation \( x\left(x^{2}+e^{x}\right) \, dy + \left(e^{x}(x-2)y - x^{3}\right) dx = 0 , \, x > 0 \), passing through the point \( (1,0) \). Then \( y(2) \) is equal to:
\( \frac{4}{4 - e^{2}} \)
\( \frac{2}{2 + e^{2}} \)
\( \frac{2}{2 - e^{2}} \)
\( \frac{4}{4 + e^{2}} \)
