Erratum: Curvature inheritance symmetry on M-projectively flat spacetimes.

This document is a correction notice for an article titled "Curvature inheritance symmetry on M-projectively flat spacetimes" published in the International Journal of Geometric Methods in Modern Physics. The authors have noted that the results presented in Section 3 of the paper hold for perfect fluid spacetimes in general, not just M-projectively flat spacetimes. Therefore, the term "M-projectively flat" should be removed from the heading, contents of Section 3, abstract, and introduction. The correct form of Equation (26) is also provided in the correction notice. [Extracted from the article]
