Buggs: I cannot run custom gnb config file from the latest user manual documentations

[ehitimum]

Issue Description

It seems if I create a custom gnb file from the latest user manual config file from this link:
https://docs.srsran.com/projects/project/en/latest/user_manuals/source/config_ref.html
and then try to run I get parse error.

Here is my config file du.yaml:

Now if I run this command sudo gnb -c du.yaml I get this INI was not able to parse ru_prach_port_id

It seems some of gnb can't understand new config or that the user manual config has problem and needs update. Anyway I am currently using one of those default configs file. They seem to work since they are old config file. Also it's confusing since I am using vlan_tag this line in past release but for new release it can't recognize this line. So I guess there maybe some bugs here.

Thank you
