Fix docstring of PseudoBlockArray

[jishnub]

julia> P = PseudoBlockMatrix(reshape([1:6;], 2, 3), [1,1], [1,2])
2×2-blocked 2×3 PseudoBlockMatrix{Int64}:
 1  │  3  5
 ───┼──────
 2  │  4  6

julia> Array(P) === parent(P)
false

Suggest parent instead of Array. We should define the convert(Array, P::PseudoBlockArray) in a separate PR.
