NGAP: Add UESecurityCapabilities IE to PathSwitchRequestAcknowledge
This IE is now used by Open5GS, so add it to the receive template.
This fixes C5G_Tests.TC_handover_inter_ngran_xn.
Note that there is also a pull request to fix the location of this IE in Open5GS. (https://github.com/open5gs/open5gs/pull/4589) Without this fix the test case will fail.
