[Dev] Comparisons with other packages

We can add a tutorial where we compare with other packages:

- https://infiniteopt.github.io/InfiniteOpt.jl/stable/
- https://jump.dev/JuMP.jl/stable/
- https://github.com/ichatzinikolaidis/CasADi.jl
- https://github.com/JuliaControl/ModelPredictiveControl.jl
- https://github.com/JuliaControl/ControlSystems.jl?tab=readme-ov-file
- https://github.com/JuliaMPC/NLOptControl.jl
- https://github.com/JuliaControl/RobustAndOptimalControl.jl?tab=readme-ov-file

Note that we should split things, see https://github.com/control-toolbox/OptimalControl.jl/issues/306.
