The original publication unfortunately contains a typo in one equation.

The equation (32)

$$\begin{aligned} {f}''=-f^{3}-\frac{R-8}{2}\qquad \quad \; (\hbox {INCORRECT}) \end{aligned}$$

should read

$$\begin{aligned} {f}''=-f^{3}-\frac{R-8}{2}f \quad (\hbox {CORRECT}) \end{aligned}$$

Since the missing \(f\) is taken into account in the succeeding arguments and computations, this never affects the content of the paper.
