The Info column shows only one NGAP/S1AP packet of several packets inside an SCTP packet
## Summary
When an SCTP packet contains several DATA chunks with different NGAP packets, the Info column shows only one NGAP packet. Other packets are hidden.
## Steps to reproduce
Open attached pcap file. There is one SCTP packet containing three NGAP messages: InitialContextSetupResponse, UplinkNASTransport, UplinkNASTransport.
## What is the current bug behavior?
NGAP dissector takes type of only one NGAP packet to fill the Info field.
The bug is similar to https://gitlab.com/wireshark/wireshark/-/issues/12144
## What is the expected correct behavior?
NGAP dissector should take types of all NGAP packet to fill the Info field. They should be separated with commas.
