Some bugs in 22.06

[TeoREN0217]

1. In the directFingerActuator demo, there is no Finger.vtk or stl file, I copy the model from SoftRobot and it worked.
2. In function def onKeypressedEvent(self, event) self._extracted_from_onKeypressedEvent_10( qOld, posA, self.angularRate) has an extra param self, you need to delete it.
3. In my SOFA version, TetrahedronSetTopologyContainer didn't work well. So I changed it as MeshTopology.

Hope this can help!
