1746: Fix Saving and loading model output example r=darsnack a=logankilpatrick

Right now, the example here: https://fluxml.ai/Flux.jl/stable/saving/#Saving-and-Loading-Models is incorrect.

```Julia
julia> model = Chain(Dense(10,5,relu),Dense(5,2),softmax)
Chain(Dense(10, 5, NNlib.relu), Dense(5, 2), NNlib.softmax)
```

is not what happens and the loading model example at the bottom expects `Chain(Dense(10, 5, NNlib.relu), Dense(5, 2), NNlib.softmax)` so this fixes this inconsistency.

 Models are just normal Julia structs, so it's fine to use any Julia storage
