Update nested_array_exercises_spec.rb (issue corrected)

[alexaldearroyo]

describe 'delete seat from grid exercise' → describe 'delete seat from row exercise'

Because

The Rspec test of the lesson gave an error because it did not find the "delete seat from grid" method, which was not present in the exercise.

The correct expected method would be: "delete seat from row". Changed the line "describe 'delete seat from grid row exercise'" to "describe 'delete seat from row exercise'".
