Reconciling PredictionRigidBody docs improvement

[Rain1950]

Hi. I suggest adding a simple line to ReconcileState function in CSP docs guide. If there is a need to set a predicted rigidbody to Kinematic, not adding line below will simply cause error (Cannot apply forces to kinematic rigidbody). I know its a simple fix but I think it should be mentioned as in games focused around physics, setting isKinematic is not that uncommon. Code below and mentioned docs chapter is here: https://fish-networking.gitbook.io/docs/manual/guides/prediction/creating-code/controlling-an-object
