Fix yaml example config file
amf_ip_address is decoded as a paramlist_def_t and not as a paramdef_t,
so in the config file it should be a list of ip addresses
In current develop just by trying to run this config file with:
sudo ./nr-softmodem -O ../../../targets/PROJECTS/GENERIC-NR-5GC/CONF/gnb.sa.band78.fr1.106PRB.usrpb210.yaml
results in a segfault.
