Config file parsing error with pcap enabled for N3 Interface

[flenz00]

Issue Description

I copied the pcap section from the configuration reference manual (https://docs.srsran.com/projects/project/en/latest/user_manuals/source/config_ref.html) but i get the following error "INI was not able to parse pcap.n3_filename"

I tried also with pcap enabled for all layers and i get the same behavior for f1u_filename "INI was not able to parse pcap.f1u_filename".

For the tagged "24.04" release those options don't exist. Simply uncomment them in the file if you wish to use the 24.04 release. They do exist in the current code in main so you can also install this version instead (recommended).

It's not clear from the issue description but i wanted to have those captures, thanks for the suggestion btw.
