[Structural] Missing contact examples

[jginternational]

At this moment we have 5 examples of the structural application in the GUI, 3 for 2D and 2 for 3D. None of them testes the Contact feature.

Could anyone provide me an example for 2D and 3D that uses contact?

I'm tagging @loumalouomega because I remember he did the feature in the past, but also all the @KratosMultiphysics/structural-mechanics team

Huum, I don' have any right now, ask @AlejandroCornejo
