Update Systems submodule to v3

[Datseris]

Easy TODO that means doing the following:

• Make sure all functions that return dynamical systems do not pass Jacobian into the constructors
• Replace all calls to @SMatrix to regular SMatrix calls, so that we can remove the StaticArrays dependency
• Ensure all functions follow the naming convention stated in the Systems docstring.

Hello i wanted to help with it. I have one question about Jacobian. Should the Jacobian be removed only from the constructor, or should the Jacobian function also be removed?

[Datseris]

keep the jacobian function with the syntax name_jacob (name of the system)

Hi! I noticed this was broken so I created a PR. Check it out and let me know is something's still not right

Question: SVector and SMatrix are from StaticArrays, right? So the dependency cannot be removed yet, can it?

[Datseris]

SVector, SMatrix come from StaticArraysCore.jl. So the StaticArrays dependency will be removed once we have stopped using the @SMatrix macro!
