typo in shell_layout example

[jarlebring]

The example in the main page has a type problem:

julia> nlist =Vector{Vector{Int}}(undef, 2) julia> nlist[1] = [1:5]
ERROR: MethodError: Cannot `convert` an object of type UnitRange{Int64} to an object of type Int64
Closest candidates are:convert(::Type{T}, ::T) where T<:Number at number.jl:6convert(::Type{T}, ::Number) where T<:Number at number.jl:7convert(::Type{T}, ::Ptr) where T<:Integer at pointer.jl:23...

The brackets should be removed.

I did not change the code, so I think the CI error is not due to changes. If you really want it to pass CI, someone with write access to travis can try to let the test run it again.

Thank you, and don't worry about the failing test - this might be some flaky test or some issues with Julia 1.5 on macOS, but should of course not be related to your changes.
