Update optimization_problems.jl

This is inconsistent with the description below, which states that the array must be sized to match the number of constraints.

I also cannot think of a reason why the constraint expressions should match the geometry of the minimisation variable (and many cases where this would not be true), so I am assuming that this is an erroneous half-sentence that can be removed.
